Let x represent the number of $10 traveler's checks she has. Which expression represents the value of the $20 traveler's checks she has?

**Reiny**, Monday, August 20, 2012 at 5:41pmnumber of 10's --- x

number of 20's ---- 22-x

10x + 20(22-x) = 300

10x + 440 - 20x = 300

-10x = -140

x = 14

She bought 14 10's and 8 20's

check: 14+8 = 22 check!

10(14) + 20(8) = 300 check!

BTW, time to update that textbook, I wonder how many people under 30 would even know what a traveler's check is.
