Question

A phone company advertises a new plan in which the customer pays a fixed amount of $ 25 per month for unlimited calls in the country and $ 0.10 per minute for international calls . Write an equation for the monthly payment a customer pays according to the new plan . Use y for monthly payment , and x for international minutes.

Type the equation in the form y=ax+b without using any spaces. Write any decimals in the form 0.00

Answer 1

y = a(.10) + 25

Explanation:

Using the equation y = ax + b.

"$25 per month for unlimited calls in the country and $0.10 per minute for international calls."

The word "per" indicating that you are multiplying this.

The only variables being multiplied are a and x.

Thus, a is the amount of minutes, x is the cost of international calls and b is the cost of unlimited calls.
