Last week at a festival, a man sold 3 times as many tie-dyed T shirts as silk screened shirts. He sold 168 shirts altogether. How many tie-dyed shirts did he sell?

Ratios shall be used

Selling 3x as many tie-dyed as silk is the equivalent of ratio 3:1 (Three tie dies for 1 silk)

Add up the total numbers in the ratio (By that I mean 3 + 1) to get 4

Divide the total number sold by 4 to get 42

Multiply 42 by 3 (The number of tie dyes sold in the ratio) to get 126

126 tie-dyed shirts were sold
