Telecharge charges $0.75 for the first minute of a call and $0.25 for each minute thereafter. If total cost for a Telecharge call is $5.75, how many minutes long was the call?

A 18
B 19
C 20
D 21
E 22



Cost of the first min = 0.75

Additional charge for each min = 0.25.

Total cost = 5.75.

5.75 - 0.75 = 5.00.

5.00 is the total cost of 0.25 slot. dividing 5 by 0.25 we can find out additional mins .

5 / 0.25 = 20.

Total duration : 20 + 1 = 21.

D is the correct answer.

= \(\frac{5.75 - 0.75}{0.25}\)

= \(20\) , Answer must be (C)
