Kyle spent 26% of his tax refund on new pair of skis. His skis cost $350. How much was his refund?

.26 (x) = 350 if you use algebra??
divide both sides by .26

If you don't use algebra, I can show you another way.

if he spent 26% x on skis which is equal to 350 we set equations

26/100 x = 350

so 13/50 x = 350

so multiplying both sides by 50/13 gives us

50/13 * 13/50 x = 350 * 50/13

x = 350*50 /13 which is equal to around 1346, or 1346.15385 to be exact
