Step 3: Solving real-world problems that involve markups
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
$23.00
$21.00
$19.00

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)
