Question

Your cell phone provider charges a monthly fee of $30. You are also charged $0.07 per minute

for each minute. Last month, Mr. Gonzales' bill was $59.40. Let m represent the total number
of minutes Mr. Gonzales used last month. Use the verbal model below to write an equation.

Answer 1

Answer:59.40

Explanation:

Answer 2

0.07m + 30 = 59.40

Mr Gonzalez used 420 minutes last month

Explanation:

To represent how much money Mr. Gonzales was charged for using minutes, use the term 0.07m.

Then, add 30 to this to represent the monthly fee:

0.07m + 30

Lastly, set this equal to 59.40 because that was his total bill for the month:

0.07m + 30 = 59.40

So, the equation for the situation is 0.07m + 30 = 59.40

Solve for m in the equation:

0.07m + 30 = 59.40

0.07m = 29.40

m = 420

So, Mr Gonzalez used 420 minutes last month.
