Answer:
Amanda would have to work 9 hours to make US$ 153
Explanation:
1. Let's review the information given to us to answer the question correctly:
Amanda's earnings = US$ 289
Hours Amanda worked = 17
2. At the same rate how many hours would she have to work to make 153 ?
Let's find the rate per hour Amanda earned, this way:
Rate per hour = Amanda's earnings/Hours Amanda worked
Replacing with the real values, we have:
Rate per hour = 289/17
Rate per hour = US$ 17
Now we can calculate how many hours Amanda would have to work to make US$ 153, this way:
Number of hours = 153/17
Number of hours = 9
