Answer:
24 hours
Step-by-step explanation:
Divide 200 by 5.50
200÷5.50=36.36 (round to the nearest decimal)
Divide 68 by 5.50
68÷5.50=12.36 (round to the nearest decimal)
So if he worked 12.4 hours to gain $68,
We then can minus 12.4 from 36.4
36.4-12.4=24
He will need to work 24 more hours in order to have enough money
