Answer:

Store D has the best deal

Step-by-step explanation:

We will divide cost per minutes

Store A: $25 for a 45 minute lesson

$25/45 minutes

$.5555555  per minute

Store B: $30 for a 1 hour lesson

1 hour = 60 minutes

$30/60  

$.5 per minute

Store C: $45 for a 1.5 hour lesson

1.5 hours* 60 minutes/ hour = 90 minutes

$45/ 90

$.5 per minute  

Store D: $80 for three 1 hour lessons

3 * 1 hour = 3 hours

3 hours * 60 minutes/ 1 hour = 180 minutes

$80/ 180 =

$.4444 per minute
