Answer:

(a)

Expression: $\frac{2hours}{6dollars} =\frac{1hour}{(x)dollars}$

Amount you earn per hour: $3

(b)

Expression: $60-27-s=15$

Amount you spend on shirt: $18

Step-by-step explanation:

(a)

Let x represent the amount you earn per hour.

$\frac{2hours}{6dollars} =\frac{1hour}{(x)dollars} \\\\2*x=6*1\\2x=6\\\\\frac{2x}{2} =\frac{6}{2} \\\\x=3$

(b)

Let s represent the amount you spent on a shirt.

$60-27-s=15\\33-s=15\\(33-s)-33=(15)-33\\-s=-18\\\\\frac{-s}{-1} =\frac{-18}{-1}\\ \\s=18$
