Solution:
Note that:
Profit percentage: S.P - C.P/C.P x 100C.P = $150S.P = $500Substitute the values into the expression to find the profit percentage.
Substituting the values.
S.P - C.P/C.P x 100=> 500 - 150/150 x 100=> 350/150 x 100=> 350/3 x 2 = 233.33%The markup percentage is 233.33%.
Your teacher announced a 50-point math quiz for tomorrow. The quiz will have 15 questions with word problems worth 4 points each and some open response questions worth 3 points each. Find the number of each type of question. You may use any of the methods to solve. Check your answer.
Answer:
5 word problems(4points each) & 10 open (3 points each)
Step-by-step explanation:
O= open response
W= word problems
W+O =15
4W + 3O = 50
multiply the first by -3 to eliminate O
-3W -3O = -45
4W + 3O = 50
AD BOTH
W = 5 ( 5 questions word problems)
O= 10 ( 10 questions open response)

I need help with 2(4/3)x8x15+280919 we couldn’t use calculator
Answer:
281,319.005
Step-by-step explanation:
Because 2 and 4/3=3 and 1/3
Because since the numerator= 4 and the denomeyer is 3 we can add another whole number so 2 and 4/3 can add whole so 2 + 1=3 wholes with 1 left over so 3 1/3.
Next we do 3 1/3 x 8 which=26.667 also known as 26 2/3
Because 2/3=66.667.
Next we so 26 and 2/3 x 15=400.005
And last 400.005 + 280,919=281,319.005
Hope this helps have a great day:)

At a concert 20% of the audience members were teenagers. If there were 1800 people at the concert, how many of those people were teenagers ?
Answer:
360 of the people were teenagers
Step-by-step explanation:
To find percentages you need to divide the number by 100
∴ 20% of 1800
=20 ÷ 100 ×1800
=360
∴ there were 360 teenagers at the concert.
Find the slope of a line going through (0, 4) and (-2, 2).
Answer:
slope = 1
Slope-intercept form: y = 1x + 4
Step-by-step explanation:
Plot the 2 points on a graph. Count the rise and the run from point A to point B. From point A, you go down 2 and to the left 2 to get to point B. Meaning, the slope is -2 over -2. (-2/-2)What is -2 divided by -2? Positive 1 From there you can use the point-slope formula and find the slope-intercept form.Hope this helps!

A line passes through the points (3,16) and (6,19). Write a linear function rule in terms of x and y for this line.
Answer:
y=1x+13
Step-by-step explanation:
First find the slope of the line. Slope is (y2-y1)/(x2-x1). Plug in 19 for y2, 16 for y1, 6 for x2, 3 for x1. So (19-16)/(6-3) is 3/3 or 1. The slope of the line is 1.
take the equation y=mx+b and plug 1 in for the slope (m). Then plug in one set of points. Using (3,16) into y=1x+b, 16=1(3) + b. Solve for b. B is 13. So the linear equation is y=1x+13.
What must be a factor of the polynomial function f(x) graphed on the coordinate plane below?
Answer:
x + 6
Step-by-step explanation:
Edit:
A moderator mentioned my answer had a mistake: turned out the question posted was incomplete. The complete question should read:
"
What must be a factor of the polynomial function f(x) graphed on the coordinate plane below?
x – 6
x – 3
x + 1
x + 6
"
As shown in the same graph, f(x) cross the x-axis at x = -6, -3 and 0.
When a polynomial crosses the x-axis at x = a, (x - a) must be a factor.
So (x + 6), (x + 3) and x are factors of f(x).
Of the options, the correct answer is x + 6.
