Question

If a cell phone company z charges a flare fee of $15 plus $0.50 per minute,the equation would be y= 0.50x + 15, where y represents total amount of money and x represents minutes, how much would it cost for 20 minutes?

Answer 1

It would cost $25 for 20 minutes.

Explanation:

The cost for x minutes of call is y, and it is given by the following equation:

y = 0.5x + 15

How much would it cost for 20 minutes?

This means that we have to replace x for 20.

y = 0.5*20 + 15 = 10 + 15 = 25

It would cost $25 for 20 minutes.
