Question

Marsha wrote three $15 checks and six for $75 each. Which of the following expressions represents the change in her bank account?

3(-15) + 6(-75)
-3(-15) + -6(-75)
-3(15) + -6(75)
3(-15) + -6(-75)

Answer 1

3(-15) + 6(-75)

Explanation:

The best expressions that represents the change in Marsha's bank account is 3(-15) + 6(-75)

Let's see first what this would amount to.

Bank Account = 3(-15) + 6(-75)

Bank Account = -45 + -450

Bank Account = -45 + -450

Bank Account = -495

This would mean that Marsha subtracted $495 from her bank account.
