Answer 1

Answer:

There are 4 Phones in the Family phone Plan.

Step-by-step explanation:

Given:

Monthly payment for each phone = $\ 22.91+\ 20= \ 42.91$

Let the number of phones in the plan be x

cost of the family data plan per month = $\ 70$

Total Monthly bill = $\ 241.64$

Total Monthly bill = Monthly payment for each phone $\times$number of phones in the plan $+$ cost of the family data plan per month

∴ The equation becomes after substituting the value,

$(42.91 \times x) + 70 = 241.64\\42.91x=241.64-70\\42.91x=171.64\\x= \frac{171.64}{42.91}\\x=4$

∴There are 4 Phones in the Family phone Plan
