Efrem worked 40 hours at his two jobs last week. he earned $20 per hour at his weekday job and $18 per hour at his weekend. he earned $770 in all. how many hours did he work at each job?

19.25 hours should be the answer

Then just do it (lol)

If you need an equation, it would be y=2x+8, y would be how long it grew, x being weeks.if you need how long he was asleep, it would be 4 weeks if he started with no beard, the equation would be x=8÷2if he did have a beard before hand, the equation would be 2w+x=8
