Telephone call to albany

Question

of a telephone call is $0.32 for the 1st minute and $0.24 for each additional minute or part of a minute. If a call between two people during peak time costs no more than $3.00, what is the greatest number of whole minutes possible for this call?

Answer 1

A phone call between these two people can be continued maximum for 12 whole minutes:

Solution:

1) $ 3.00 - $ 0.32 = $2.68 - 1st minute

2) $2.68 / $0.24 = 11.16 (about) Cut off the decimal part = 11 whole minutes

3) 1 min + 11 min = 12 minutes

Check:

$0.24 * 11 = $2.64

$0.32 *1 = $0.32

Total is: $2.64 + $0.32 = $2.96

Answer 2

m represents the number of minutes after the first.

3.00 = 0.32 + 0.24m

Can you solve for m and answer?
