There were 320 T-shirts at a shop. ³₄ of them were without collars. T-shirts without collars were priced at $8 each. T-shirts with collars were priced at $12 each. The shop owner sold ¹₆ of the T-shirts without collars and ³₅ of the T-shirts with collars. How much did he collect from all the T-shirts he sold?
Number of T-shirts = 4 u

4 u = 320

1 u = 320 ÷ 4 = 80

Number of T-shirts without collars
= 3 u
= 3 x 80
= 240

Number of T-shirts without collars sold 
= ¹₆ x 240
= 40

Number of T-shirts with collars
= 1 u
= 1 x 80
= 80

Number of T-shirts with collars sold
= ³₅ x 80
= 48

Amount that the shop owner collected from the sale of the T-shirts without collars
= 40 x 8
= $320

Amount that the shop owner collected from the sale of the T-shirts with collars
= 48 x 12
= $576

Total amount that the shop owner collected from all the T-shirts he sold
= 320 + 576
= $896

Answer(s): $896
