Heather has a family phone plan. the monthly payment for each phone is 22.91 per month plus a monthly line fee of $20 per phone. the cost of the family data plan is $70 per month and her monthly bill is $241.64. wrote and solve an equation to find how many phones are on the plan.

The number of phones on the family phone plan given in the question is;

4 phones

We are given;

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

Monthly cost of family data plan = $70

Total Monthly bill = $241.64

If the number of phones on the plan is p, then we have;

42.91p + 70 = 241.64

Using substitution property of equality, subtract 70 from both sides;

42.91p + 70 - 70 = 241.64 - 70

42.91p = 171.64

divide both sides by 42.91 to get;

p = 171.64/42.91

p = 4 phones

Thus, in conclusion, there are 4 phones on the plan.
