a student has \$8 to spent on a phone call.the cost of the call is \$0.34 for the first minute and \$0.24 for each additional minute. how long can the student talk on the phone?

\$8-\$0.34=\$7.66
\$7.66/\$0.24=31.9
so i guess its about 31 to 32 minutes
\$0.24*31=\$7.44
\$7.44+\$0.34=\$7.78 that's to low
then i trie
\$0.24*32=\$7.68
\$7.68+\$0.32=\$8.02

31 minutes + 1 minute (first minute) = 32 minutes
