Question

Last week, Clay wrote 4 checks for $20 each from his checking account, withdrew another $30, and finally made a deposit of $96. What was the change in the balance of his account over the week?

Answer 1

Explanation:

taking money from his account is a minus operation. it lowered the balance.

adding money (like a deposit) is a plus operation. it increases the balance.

so, he did

-4×20 - 30 + 96 = -80 - 30 + 96 = -14

his balance decreased by $14 over this week.

Answer 2

$-14

Explanation:

4(20)= 80

30+80= -110

-110+96

-14
