Final answer:
Calvin earned $288 from the first job and $480 from the second job, making a total of $768 from both jobs last week.
Step-by-step explanation:
Calvin worked a total of 40 hours last week, with 16 hours at a job paying $18 per hour and the remaining hours at a job paying $20 per hour. To calculate the total amount of money Calvin made, we'll first determine the earnings from each job separately and then sum them.
For the first job:
- 16 hours * $18 per hour = $288
For the second job, he worked the remaining 24 hours (since 40 - 16 = 24):
- 24 hours * $20 per hour = $480
Add the earnings from both jobs to find the total:
Therefore, Calvin made a total of $768 from both jobs last week.
