John sold 4 times as many Kansas City Chief T-shirts as San Francisco 49er T-shirts. He sold 250 shirts altogether. How many Kansas City Chief shirts did he sell?

He sold 200 Kansas City Chief T-shirts.

Step-by-step explanation:

Let x represent the number of Kansas City Chief T-shirts that John sold.

Let y represent the number of San Francisco 49er T-shirts that John sold.

He sold 250 shirts altogether. This means that

x + y = 250- - - - - - - - - - -- - -1

John sold 4 times as many Kansas City Chief T-shirts as San Francisco 49er T-shirts. This means that

x = 4y

Substituting x = 4y into equation 1, it becomes

4y + y = 250

5y = 250

y = 250/5 = 50

x = 4y = 4 × 50

x = 200

72 is the answer to this problem
