Answer:

He spent on 16 minutes

Step-by-step explanation:

Given

Base\ Amount = \$40

Charge = \$0.5 per minute

Total = \$48

Required

Determine the number of minutes

Let the number of minutes be n

<em>If 1 minute costs $0.5</em>

<em>n minutes would cost $0.5n</em>

The relationship between the given parameters is

Total = Base\ Amount + Charges

Substitute values for each of the above

48 = 40 + 0.5n

Solve for 0.5n

0.5n = 48 - 40

0.5n = 8

Solve for n

n = 8/0.5

n = 16

<em>He spent on 16 minutes</em>
