Question

Four of Professor Chaplin's students are combining their money to buy him a retirement gift. Each student puts $4 into the pot. The gift they find only ends up costing $13. Which of the following is a process the students can use to find how much change each of them will get back after they purchase the gift?

Answer 1

A. Divide the cost of the gift ($13) by $4; multiply the result by the number of students (4).
B. Add the number of students (4) to $4; subtract $13 from that total and divide the result by the number of students.
C. Add together the number of students (4) and the cost of the gift ($13); divide that total by the number of students (4).
D. Multiply the number of students (4) by $4; subtract $13 from that total and divide the result by the number of students (4).

Answer 2

You have 4 students...each pitching in 4 dollars
so 4x4 = total amt of dollars raised
your gift costs 13 dollars, so the difference (change) is?
but remember this change is (total amount for all 4 students), to find change for each student you split it into 4
