Question

The change in the total amount of Suki's allowance balance over the course of four weeks is shown in the table.

Week Change ($)
1 25.25
2 ─5.75
3 12.40
4 ─14.35


Based on the average change in her allowance balance per week, how much money can Suki expect to save or spend over the course of a year?

Answer 1

To get the average you add all numbers up then divide by the amount of numbers you have. In case it's 4 then you get your average dollar amount then you can calculate the amount for the years by multiplying it by 52 because there is 52 weeks in a year.
