Question

A bank account balance decreases $735

in 3 weeks. What is the average daily
change in the balance?

Answer 1

35 because there’s 21 days in 3 weeks so you divide 735 by 21 and you get 35

Answer 2

$35

Explanation:

To answer this question first calculate how many days are in 3 weeks. To do this multiply 7 by 3 because there are 7 days in a week and there is 3 weeks total. This equals 21, so the total period of time is 21 days. Then, divide 735 by 21 to get the amount it decreases every day on average. 735 divided by 21 is 35, which is your final answer.
