Clay and Timmy had $318 altogether. Timmy had $18 less than Clay. After Timmy spent some money at the store, Clay had 6 times as much money as Timmy. How much money had Timmy spent at the store?

Let x = Clay's money

Let y = Timmy's money

x + y = 318 (1)

y = x - 18 (2)

Substitute (2) to (1):

x + x - 18 = 318

2x/2 = 336/2

x = 168

From (2): y = x - 18

y = 168 - 18

y = 156

Let z = amount of money Timmy spent at the store

(150 - z) = 168

900 - 6z = 168

732/6 = 6z/6

z = $122
