A local shoe store buys shoes at a wholesale price and then marks them up 80% to calculate the retail price. The wholesale price varies, depending on the quantity of shoes purchased. (2 points)

Quantity

0-20 pairs

21-40 pairs 41-60 pairs 61-80 pairs

81 or more pairs

Wholesale Price, (per pair) $25.00 each $23.00 each $21.00 each $19.00 each $17.00 each

Write an equation that could be used to find the retail price for each range. How do you know the equation will work consistently for each range? (2 points)

1 answer

Let R be the retail price and W be the wholesale price. The equation that could be used to find the retail price for each range is:

R = W + (0.8 * W)

This equation will work consistently for each range because it takes into account the 80% markup on the wholesale price for all quantities of shoes.
