There were 160 T-shirts at a shop. ³₄ of them were with collars. T-shirts with collars were priced at $5 each. T-shirts without collars were priced at $4 each. The shop owner sold ³₄ of the T-shirts with collars and ³₅ of the T-shirts without collars. How much did he collect from all the T-shirts he sold?
Number of T-shirts = 4 u

4 u = 160

1 u = 160 ÷ 4 = 40

Number of T-shirts with collars
= 3 u
= 3 x 40
= 120

Number of T-shirts with collars sold 
= ³₄ x 120
= 90

Number of T-shirts without collars
= 1 u
= 1 x 40
= 40

Number of T-shirts without collars sold
= ³₅ x 40
= 24

Amount that the shop owner collected from the sale of the T-shirts with collars
= 90 x 5
= $450

Amount that the shop owner collected from the sale of the T-shirts without collars
= 24 x 4
= $96

Total amount that the shop owner collected from all the T-shirts he sold
= 450 + 96
= $546

Answer(s): $546
