Question

Fred's family wants to switch cell phone plans. Hot Spot Mobile is offering a one-time discount of $50 for families that use multiple phones with their service. Fred's family uses 5 phones, and the salesperson said the first month's payment, which includes the discount and the regular monthly rate for each phone, will be $62.25. What is the regular monthly rate for each phone?
$
per month

Answer 1

Let r be the monthly rate per phone. Then 5r − 50 = 62.25, so 5r = 112.25 and r = 112.25/5 = 22.45.

$22.45 per month
