You are comparing prices for cable companies. Company A charges a flat fee of $45 and a monthly charge of $65. Company B charges $80 per month. For what number of months will the cost be the same?.

Respuesta :

Answer: 3 months

Step-by-step explanation:

Let x be the number of months and A and B the total costs for each service.

A = 45 + 65x

B = 80x

We want to know the months that would make A = B:

A = B, solve for x, months.

45 + 65x = 80x

45 = 15x

x = 3 months

After 3 months, Company A will be less expensive.
