Question

Chitchat wireless charges $0.30 per minute plus a monthly base fee. In September, Maggie used 120 minutes and her bill was $51. Write and solve an equation to find the cost of Maggie uses 165 minutes in October.

Answer 1

Explanation:

Charger per 60 sec. = $0.30

Total monthly bill(Sept.)

= $51

0.30 × 120 = 51-36

= 15 (Monthly base fee)

October bill = 165 × 0.30

= 49.5 - 15

October usage bill =$34.5
