Mike paid $18.00 before taxes for 5 photo albums. his sister wants to buy two of the same type of album. what amount should she expect to pay before taxes? $3.60 $7.20 $9.00 $13.00

First find how much each photo album costs individually.
$18.00 ÷ 5 albums = $3.60

Multiply $3.60 by 2 to find how much 2 albums of the same type would cost.
$3.60 × 2 = $7.20

Mike's sister should expect to pay $7.20 for two albums.

Here’s the answer. you’re supposed to use 2900 times the interest rate and then add your original amount of money. now you get 2997.15
