The sellers have agreed to give the buyer a carpet allowance to replace the family room carpet. They will allow $19.95 per square yard for carpet plus $5 per square yard for pad and installation. If the family room is 22'6x15', how much will it cost the sellers?

Total number of T-shirts= 200

Cost per T-shirt (without shipping ) = $2.80

Shipping cost per t-shirt ; 5% of a T-shirt = 0.05 *2.80 = $0.14

Total cost of T-shirt (shipping included) = 2.80 +0.14 = $2.94

Markup = 150% of total cost = 1.50 * 2.94 = $4.41

To get the price at which Michelle will sell each T-shirt , add total cost  to the markup; 2.94 +4.41 = 7.35.

Therefore, selling price will be $7.35
