Last week at a​ festival, a man sold 5 times as many​ tie-dyed T-shirts as​ silk-screened shirts. He sold 210 shirts altogether.
Alexeev081 [22]

Answer:

The number of​ tie-dyed shirts is 175

Step-by-step explanation:

This question can be solved using a system of equations.

I am going to say that:

x is the number of tie-dyed T-shirts sold.

y is the number of  silk-screened shirts.

He sold 210 shirts altogether.

This means that x + y = 210

Last week at a​ festival, a man sold 5 times as many​ tie-dyed T-shirts as​ silk-screened shirts.

This means that x = 5y or y = \frac{x}{5}

How many​ tie-dyed shirts did he​ sell?

This is x.

x + y = 210

x + \frac{x}{5} = 210

\frac{5x + x}{5} = 210

6x = 210*5

x = \frac{210*5}{6}

x = 175

The number of​ tie-dyed shirts is 175
