Gail received a 7% raise last year. If her salary is now $27,285, what was her salary last year?

Last year's pay was 100% of last year's pay (obviously). Since she is now getting 7% more, then she is now getting 107% of last year's pay.

Pick a variable for the amount of last year's pay. Translate the given relationship:

. . . . .(this year's pay) is (107%) of (last year's pay)

...into a linear equation, and solve for the value of the variable.
