Edgar has already spent 6 minutes on the phone, and he expects to spend 1 more minute

with every phone call he routes. If he routes 40 phone calls, how much time will Edgar have

spent on the phone in total?

Answer 1

34 minutes

Explanation:

Given

`Time\ Spent = 6`

`Phone\ Calls = 40`

Required

Number of minutes left to spend (x)

Since there's only 1 minute left to spend on every other call;

Time left = x * 1

Time left = x

The required can further be calculated using:

`Time\ Spent + Time\ Left = Phone\ Calls`

This gives:

`6 + x = 40`

Subtract 6 from both sides

`x = 40 - 6`

`x = 34`

Hence, there are 34 minutes left to spend
