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?

i think the answer is...

$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 thats to low

then i trie

$0.24*32=$7.68

$7.68+$0.32=$8.02

thats to high so i dont know please help me
