a) 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 $25.00 each $23.00 each $21.00 each $19.00 each $17.00 each (per pair)

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?

Let "x" be the quantity of shoes purchased. The equation that could be used to find the retail price for each range is:

Retail price = (Wholesale price + (Wholesale price * 0.8)) * x

This equation will work consistently for each range because it takes into account the wholesale price for each range and adds a markup of 80% to calculate the retail price. The quantity "x" is multiplied to account for the number of pairs purchased in each range.
Is that right???
Apologies for the mistake. The correct equation to find the retail price for each range would be:

Retail price = Wholesale price + (Wholesale price * 0.8)

This equation will work consistently for each range because it adds a markup of 80% to the wholesale price, which is the same for all ranges.

Apologies for the confusion. The correct equation to find the retail price for each range would be:

Retail price = Wholesale price + (Wholesale price * 0.8)

This equation will work consistently for each range because it adds a markup of 80% to the wholesale price, which is the same for all ranges.
