Question

Tony has $727.29 in his checking account. He must maintain a $500 balance to avoid a fee. He wrote a check for $248.50 today. Write and solve an inequality to solve for the least amount of money he needs to deposit to avoid a fee.

727.29 + 248.50 − x ≥ 500; x ≥ $475.79

727.29 + 248.50 − x ≤ 500; x ≤ $475.79

727.29 − 248.50 + x ≥ 500; x ≥ $21.21

727.29 – 248.50 - x ≤ 500; x ≤ $21.21

Answer 1

We can immediately cross out a and b, because "he wrote a check for 248.50" that means he "lost" 248.50

Answer 2

Correct?

Answer 3

yes

Answer 4

Ok now, to avoid a fee, his balance has to be at least 500, so if his balance is less than 500 (as indicated by the last letter choice) he will get a fee

Answer 5

No, lets work this out
oops, he is going to get fined. He needs to add an x amount of money to his account to make the 500 dollar cut.
