Answer:

9 years

Step-by-step explanation:

You want to find t such that y=10.

10 = 7.67(1.03)^t

10/7.67 = 1.03^t . . . . . divide by 7.67

log(10/7.67) = t·log(1.03) . . . . . . take logs

log(10/7.67)/log(1.03) = t ≈ 8.9743 . . . . . years

After about 9 years, the employee will be earning $10 per hour.
