There were 350 T-shirts at a store. ⁴₇ of them were with collars. T-shirts with collars were priced at $8 each. T-shirts without collars were priced at $9 each. The store owner sold ¹₄ 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 = 7 u

7 u = 350

1 u = 350 ÷ 7 = 50

Number of T-shirts with collars
= 4 u
= 4 x 50
= 200

Number of T-shirts with collars sold 
= ¹₄ x 200
= 50

Number of T-shirts without collars
= 3 u
= 3 x 50
= 150

Number of T-shirts without collars sold
= ³₅ x 150
= 90

Amount that the store owner collected from the sale of the T-shirts with collars
= 50 x 8
= $400

Amount that the store owner collected from the sale of the T-shirts without collars
= 90 x 9
= $810

Total amount that the store owner collected from all the T-shirts he sold
= 400 + 810
= $1210

Answer(s): $1210
