Answer:
The Jones family paid $164
Step-by-step explanation:
At smith mountain boat lake boat rentals, it cost $25 per hour to rent a platoon boat plus a one time charge for cleaning . The Bengel family rented the boat from 11 am - 6:30 pm and their total charge was $226.50.
The boat cost $25 per hour plus a one time charge for cleaning.
let
one time charge = a
number of hours anyone rent the boat = b
total charge for the boat rent = a + 25b
In the case of Bengel they rented the boat from 11 am - 6:30 pm which is 7 and 1/2 hours = 7.5
Their total charge = $226.50
where b = 7.5
226.50 = a + 25(7.5)
226.50 = a + 187.5
a = 226.50 - 187.50
a = $39
The one time charge for the boat is $39.
Jones family rent
Jones family rented the boat from 8 am - 1 pm, the number of hours they used is 5 hours .
total charge = 39 + 25(5)
total charge = 39 + 125
total charge = $164
The Jones family paid $164
