F. Evelyn is running a snack sale during lunch to raise money for charity. She is selling hot Cheetos with
cheese for $1.50 each and chili-cheese fries for $2.50 each. At the end of the day she has raised $150 and
sold 80 items. How many of each item did she sell?
The number of hot Cheetos with cheese sold is 50, while the number of chilli cheese sold is 30.
What is a System of equations?A set of simultaneous equations, often known as a system of equations or an equation system, is a finite collection of equations for which common solutions are sought.
Let the number of hot Cheetos with cheese sold be represented by x, while the number of chilli cheese is represented by y.
It is given that the total number of items sold by Evelyn during the event is 80. Therefore,
x + y = 80
x = 80 - y
Given that the cost of hot Cheetos with cheese is $1.50, while the cost of chilli cheese is $2.50, also the total amount that was collected in the event is $150. Therefore, we can write,
1.50x + 2.50y = 150
1.50(80 - y) + 2.50y = 150
120 - 1.50y + 2.50y = 150
1y = 150 - 120
y = 30
Substitute the value of y in the first equation,
x + y = 80
x + 30 = 80
x = 80 - 30
x = 50
Hence, the number of hot Cheetos with cheese sold is 50, while the number of chilli cheese sold is 30.

The number of hot Cheetos with cheese sold is 50, while the number of chili cheese sold is 30.
What is a System of equations?
"A system of equations is a collection of two or more equations with a same set of unknowns. In solving a system of equations, we try to find values for each of the unknowns that will satisfy every equation in the system. The equations in the system can be linear or non-linear."
Let the number of hot Cheetos with cheese sold be represented by P, while the number of chili cheese is represented by Q.
It is given that the total number of items sold by Evelyn during the event is 80. Therefore,
P + Q = 80
P = 80 - Q --------- (1)
Given that the cost of hot Cheetos with cheese and chili cheese
So the equation
1.50P + 2.50Q = 150 --------- (2)
Put the equation (1) in equation (2)
1.50(80 - y) + 2.50y = 150
120 - 1.50Q + 2.50Q = 150
1Q = 150 - 120
Q = 30
Substitute the value of Q in the first equation,
P+Q = 80
P + 30 = 80
P = 80 - 30
P = 50

Jessica is building a cardboard box that has a length of 16 inches, width of 9 inches, and height of 4 inches. If she decided to triple the height of the box, how much more cardboard does she need?
Answer:
Step-by-step explanation:
I assume you have a prism with a length of 16 inches, a width of 9 inches and a height of 4 inches and you want to know the surface area
1st...convert these to feet
16 in = 1 + 1/3 ft = 4/3 ft
9 in = 3/4 ft
4 in = 1/3 ft
And the surface area =
2 [ 4/3 * 3/4 + 4/3 * 1/3 + 3/4* 1/3 ] =
2 [ 1 + 4/9 + 1/4 ] =
2 [ ( 36 + 16 + 9 ) / 36 ] =
(1/18) ( 61) =
(61 / 18) sq ft ≈ 3.38 sq ft.

audio The number of necklaces Cameron can make varies directly with the amount of time he spends making the necklaces. He can make 6 necklaces in 1/2 hour. 2 Problem Read aloude How many necklaces can Cameron make in 7 hours? A 84 B 76 C 1 5 7 D 12
Answer:
84 Necklaces
Step-by-step explanation:
1/2 Hour = 6 Necklaces - (We want to convert this from 1/2 or 30 min to 1 hour)
1/2 x 2 = 1 Hour / 6 x 2 = 12 Necklaces
1 Hour : 12 Necklaces <- This is our ratio
With this ratio, we can now multiply the hour by the number of hours we have in this case 7.
1 x 7 = 7 Hours / 12 x 7 = 84 Necklaces < - We need to multiply the same number to both sides to keep the equivalent ratio.

Aunjoli has $30 to spend at the grocery store.
If plums cost $1.50 per pound, what is the greatest number of pounds of plums she
can buy?
Answer:
20 pounds
Step-by-step explanation:
she has 30 dollars, and 1.50 is how much each pound is
we should divide 30 (how much she can spend) by 1.5 (cost of pound) so that we know how many pounds she can buy using all the money.
after we divide, we get a result of 20, so she can buy 20 pounds for 30 dollars.
lets check.
we can multiply 20 (pounds she can buy) by 1.5 (money per pound) and that should get us to 30 dollars.
20*1.5=30

The cost of playing pool increases with the amount of time using the table. Identify the independent and dependent quantity in the situation.
a) cost; time using table
b) cost; number of players
c) time using table; cost
d) number of games; cost
Answer:
c) time using table; cost
Step-by-step explanation:
An independent quantity is the variable that can be controlled and changed. A dependent quantity is not controlled and is based on the changes to the independent quantity.
First, decide which quantity can be controlled. In this situation, the player gets to choose the amount of time for which they play. This means that the time using the table must be the independent quantity because it is controlled by the player.
The cost cannot be controlled. It is solely based on the amount of time played. This means that the cost is the dependent quantity in this situation.
Marvin designed and built an 8.25-foot by 12.5-foot deck for $1.270. What was the cost of the deck per square foot?
The cost of the rectangular deck is: $0.08 per square foot.
What is the Area of a Rectangular Shape?Area of rectangular shape = length × width
The deck is rectangular.
Thus:
Cost of the deck per square foot = area of rectangular deck/total cost of deck.
Area of rectangular deck = 8.25 × 12.5 = 103.125
Cost of the deck per square foot = 103.125/1,270 = 0.08
Therefore, the cost of the rectangular deck is: $0.08 per square foot.
