John needs to take 2 pills a day. One pill costs $1.5. The insurance covers 40% of the cost. How much does he pay in a 30-day month?
A step-by-step solution is:
54
It cost 2 * 1.

5 = $3 a day.

So it cost 3 * 30 = $90 per day.

Insurance covers 90 *.

4 = $36.

So he pays 90 - 36 = $54 a month.

.

Thus, the answer is 54
