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.
