If Valerie has a shoe business and bought a pair of shoes for $50 and wanted to mark them up by 80%, what price is she selling the shoes for?

She will sell the shoes for 90 dollars

Step-by-step explanation:

First find the markup

50 * 80%

50 *.8

40

Add this to the original price

50+40 = 90

She will sell the shoes for 90 dollars

A) 0.5(2) + 80 = 81

B) 83

C) f(4) = 0.5(4) + 80 = 82

g(x) = 2x + 79

Slope: (83-81)/(2-1) = 2

y = 2x + c

When x = 1, y = 81

81 = 2 + c

c = 79

g(x) = 2x + 79

g(4) = 2(4) + 79 = 87

Since 87 > 82,
