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 if Maggie uses 165 minutes in october.

Answer 1

Answer: 120(.3) + x= 51

165(.30) +x=y

y= 64.5

Explanation:

120(.30) + x = 51 is the first equation. Solve it and get 15 for x which is the base fee.

Plug it into 165(.30) + 15 = y to get her October cost.
