Answer:
In order to have enough for the trip, Amanda must save $58 each week.
Explanation:
This problem can be solved by a simple rule of three. The problem states that in 25 weeks, Amanda wants to save $1450. To know how much she must save per week, we must find the equivalent of this in one week. So we have the following rule of three:
25 weeks - $1450
1 week - $x



In order to have enough for the trip, Amanda must save $58 each week.
