Answer:
For a length of total of 4 hrs, the budget of $200 will not exceed.
Step-by-step explanation:
Here, the first half hour charge for repairing = $60
The next hour charge = $40 her hour
Total budget to be spent by Blue Mountain Camp = $200
Now, here, the cost of 0.5 hour = $60
So, the amount left after 0.5 hour repair = $200 - $60 = $140
Let us assume we can hire the service for m hours in $140
Cost of 1 hour charge = $40
Cost of m hour charge = m X ( 1 hour charge) = m x ($40) = 40 m
⇒ 40 m = 140
or, m= 140/40 = 3.5, or m = 3.5
⇒ In $140 left, they can get a service of 3.5 hours at $40 per hour.
Now, the total hours of services hired = 0.5 hour in $60 + 3.5 hr in $140
= 0.5 hr + 3.5 hr = 4 hrs
Hence, for a length of total of 4 hrs, the budget of $200 will not exceed.
