Total amount to be invested = $2,500.
First given price for a printed shirt = $18.
Number of shirts that they can buy = Total money ÷ Price of each shirt.
a) For unit price $18 number of shirts can buy = 2,500/18 = 138.89, so approximately 138 ( because it's less than 139).
Therefore, with unit price $18 the maximum number of shirts can buy = 138 shirts.
a) For unit price $15 number of shirts can buy = 2,500/15 = 166.67, so approximately 166 ( because it's less than 167).
Therefore, with unit price $15 the maximum number of shirts can buy = 167 shirts.
a) For unit price $11 number of shirts can buy = 2,500/11 = 227.27, so approximately 227 ( because it's less than 228).
Therefore, with unit price $11 the maximum number of shirts can buy =227 shirts.
Therefore, with least unit price $11 , maximum number of shirts could be buy and that is 227 shirts which is over 200.
