The wholesale price for a shirt is $8.50 . A certain department store marks up the wholesale price by 60%. Find the price of the shirt in the department store. Round your answer to the nearest cent, as necessary.

Step-by-step explanation:

The original cost to the store was 8.50

It was marked up 60% (of 8.50)

So the Customer cost (call CC in the equations below) was

CC = 8.50 + 60/100 * 8.50

CC = 8.50 + 5.1

CC = 13.60

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x
