Answer: Mark up percent = 20%
Step-by-step explanation:
Given: Cost price of each T-shirt = $5.00
Amount required = $450
Total students = 75
Market price for each T-shirt to raise the required amount = (Amount required ) ÷ 75
= $450 ÷ 75
= $ 6
Mark up percent = 
Hence, Mark up percent = 20%
The answer is: " - (4/3) " .

Explanation:
____________________________________
The original equation given has a slope of (3/4).
Note: We know this since the equation for the slope of the line is written in "slope-intercept form" ; also known as: "point-slope form"; that is:
" y = mx + b " ; in which "m" (the coefficient of "x") is the slope.
____________________________________________________
The slope of a line PERPENDICULAR to an equation, when written in "slope-intercept form", is the "negative reciprocal" of the slope of the original line.
Hence, the negative reciprocal of "(3/4)" is: "-(4/3)" .
