the first three minutes of a call cost $1.75. each additional minute or portion of that call costs $0.50. how many minutes can they call for $8.25

Question

Just trying to do a inequality problem 

Answer 1

Divide $8.25 by $1.75; this gives you more than 4 but less than 5. Assume 4*3, that means you can get 12 minutes evenly at a cost of $7.00

You still have $1.25 left over, so you can get 2 more minutes for another $1, this gives you 14 minutes.

Now you only have $0.25, which is not enough money to pay for even a portion of a call.

You can call for 14 MINUTES with $8.25

Answer 2

16 is the answer.  8.25 - 1.75 (first 3 minutes) = 6.50 then 6.50 divided  by .50 = 13 minutes
