Final answer:
To estimate how much the student must save each month to pay for the new appliances that cost $3,100, divide the total cost by the number of months the student wants to save for.
Step-by-step explanation:
To estimate how much the student must save each month to pay for the new appliances that cost $3,100, we can divide the total cost by the number of months the student wants to save for. Let's say the student wants to save for 10 months.
So by calculation with the given data we get:
3100 / 10 = 310
The monthly savings necessary would be $310.
