Question

Mr. Ramadhan earns $15.25 per hour for the first 40 hours he works for the week. He earns 1.5 times that amount per hour for each hour beyond 40 hours in a week. Last week Mr. Ramadhan worked 47.5 hours. How much did he earn? **

Answer 1

Answer: $781.56 (usual decimal) / $781.5625 (original decimal)

Explanation:

Step One: Find the amount of money earned in 40 hours

$15.25 × 40 = $610

Step Two: Find the amount of time over 40 hours

47.5 - 40 = 7.5 hours

Step Three: Find the amount of money earned per hour beyond 40 hours

1.5 × $15.25 = $22.875

Step Four: Find the amount of money earned beyond 40 hours

$22.875 × 7.5 = $171.5625

Step Five: Add all the amount of money together

$610 + $171.5625 = $781.5625

Step Six: Rounding

$781.5625 ≈ $781.56

**Disclaimer** Usually the amount of money ends at two decimal places. However, I am not sure about your rules applied in the mathematics of rounding. Therefore, if you are totally fine with having over normal amounts of decimals, then it would be your choice.

Hope this helps!! :)
