Explanation:

Problem 5

Step1: Calculate earned amount so far

$\text{Earnings} = 24 \times 11.25 = 270$

Step2: Find remaining amount needed

$\text{Remaining} = 370 - 270 = 100$

Step3: Calculate required hours

$\text{Hours} = \frac{100}{11.25} \approx 8.89$

Step4: Round up to whole hours

Since hours must be whole, round to 9.

Problem 6

Step1: Calculate earned amount so far

$\text{Earnings} = 7 \times 7.25 = 50.75$

Step2: Find remaining amount needed

$\text{Remaining} = 93 - 50.75 = 42.25$

Step3: Calculate required hours

$\text{Hours} = \frac{42.25}{7.25} \approx 5.83$

Step4: Round up to whole hours

Since hours must be whole, round to 6.
