Answer 1

4 weeks

38 hours

Explanation:

First determine how much he makes each week

8.10 * 9.5 =76.95 per week

Multiply this by w to determine the amount he will make in w weeks

76.95w

This must be greater than or equal to the amount he needs

76.95w ≥299.99

Divide each side by 76.95

76.95w/76.95 ≥299.99/76.95

w≥3.89851

Rounding to a whole number of weeks

4 weeks

4 weeks at 9.5 hours =

4* 9.5 =38 hours
