Question 662783: you earn $20 per hour landscaping a yard.You pay $.50 in bus fare each way. How many hours must you work to end up with $117?

You can put this solution on YOUR website! This is a weird math problem, but I'll try my best.
I'm trying hard to guess what is expected for an answer.
Is it expected to be realistic?
How accurately would you measure the time worked?
Are you expected to end up with exactly $117?
Or is it at least $117, without working an hour more than necessary?
Working 5 hours, you would get paid $100. Not enough.
Working 6 hours, you would get paid $120.
Working 7 hours, you would get paid $140.
Working  hours, you would get paid $140.
Each round trip costs you $1.
I'd say you must work  hours, split into 3 work sessions.
That would give $120 in gross earnings minus $3 in travel costs, for a net income of $120-$3=$117.
Maybe you would like to work 4 hours one day, over the weekend, plus one hour on each of two workdays, after school.
I do not see any other realistic solution.
I expect that work would be paid by the whole hour or the half hour, not in other fractions of an hour.
If it is not supposed to be realistic,
and you need to end up with exactly $117,
then you could do the work in just one session (of less than 6 hours).
That would mean you need to earn just an extra $1 for the bus fare.
Earning $117+$1=$118 at $20 per hour would require
118/20=5.9 hours = 5 hours and 0.9 hour X (60 minutes/hour)= 5 hours and 54 minutes.
Or you could work, a little longer, but split your work into more than one session.
Each extra session would cost you $1 in bus fare,
which you could make up with  of an hour (3 minutes) of extra work.
You could even work 6 hours and 15 minutes over 8 sessions for a gross payment of $125, that taking out $8 for bus fare, would leave you $117.
