Step-by-step explanation:

Assuming t = two years

3% of $22.00 =.66

step-by-step

3 percent * 22.00 =

(3:100) * 22.00 =

(3*22.00) : 100 =

66:100 = 0.66

A).66x2 = 1.32 + 22.00 = 23.32

after 2 years the plumber will make $23.32 per hour

B).66x8 = 5.28 = 22.00 = 27.28

after 8 years the plumber will make $27.28 per hour
