Practice makes perfect
Let's write an inequality for Jackson's situation. Let w be the number of withdrawals he can make. Notice that the total cost must be less than or equal to $87.
Verbal Expression
Algebraic Expression
Monthly service fee ($)
6
Total fees paid for w withdrawals at out-of-network ATMs ($)
2w
Total amount withdrawn from out-of-network ATMs ($)
20w
Maximum amount of money that can be withdrawn
6+20w+2w≤ 87
We can simplify our inequality.
6+20w+2w≤ 87 ⇔ 6 + 22w ≤ 87
Now, let's solve it for w.
