Question

Michael starting a savings account with $300. After 4 weeks he had $350 and after 9 weeks he had $400. What is the rate of change in his savings account per week

Answer 1

The rate of change in Michael's savings account per week is $12.50.

Step-by-step explanation:

To find the rate of change in Michael's savings account per week, we need to determine how much the account balance increased per week. We can subtract the initial balance from the final balance and divide that by the number of weeks:

Rate of change per week = (Final balance - Initial balance) / Number of weeks

Using the given information, the rate of change per week is:

(350 - 300) / 4 = 50 / 4 = 12.5

Therefore, the rate of change in Michael's savings account per week is $12.50.

Answer 2

$12.5 per week

Step-by-step explanation:

(300)+12.5 +12.5+12.5+12.5=350
