Kelly wants to buy 3 boxes of cereal. She wants to use the coupon that says buy one get on half off. If each box of cereal costs 4.75 how much will she pay in total

$11.88

Step-by-step explanation:

Given that Kelly would get one box of cereal half off if she buys one, then we must take that into account.

Box 1: $4.75

Box 2: $4.75 ÷ 2 = $2.38

Box 3: $4.75

Now we simply add the totals:

4.75 + 2.38 + 4.75 = $11.88
