Steve recently received a raise of 6% of his salary at his part-time job. He now earns $38.69 per week. How much did he earn per week before his raise?

Suppose he used to make $ X before the raise. After getting 6% raise he makes $ 1.06*X now which is equal to $38.69.

Therefore using proportions,

X / 1.06 X = ? / 38.69

? = 38.69 * X \ 1.06*X= 38.69 / 1.06 = $ 36.5
