Jake agrees to work part of his debt off.  He owed someone $100 but paid them $40 before agreeing to work off the rest.   He worked for $15 an hour.  How many hours did he have to work?
Ҷейк розӣ мешавад, ки қисми қарзашро кор кунад. Вай ба касе $100 қарздор буд, аммо пеш аз розӣ шудан ба кор кардани боқимонда $40 пардохт кард. Вай бо $15 дар як соат кор кард. Вай чанд соат бояд кор мекард?
How much does he have to work off? ** He has to work off $100-$40=$<<100-40=60>>60.
How many hours does he have to work? ** So he has to work $60/15=<<60/15=4>>4 hours
