Answer:
The given equation in slope intercept form is
226.50 = 7.5 (25) + 39
Step-by-step explanation:
The SLOPE INTERCEPT form of a equation is y = m x + c
The per hour cost for rental of boat = $25 per hour
Let us assume the one time cleaning charge = $ k
The boat is booked from 11 am : 6 : 30 pm
So, the number of hours boat was used = 7 . 5 hours
Hence, the cost for engaging boat for 7.5 hours
= 7.5 (cost per hour ) = 7.5( $25) = $187 . 5
Total amount paid by the family = $226. 50 = Fixed cleaning charge + rate for 7.5 hours
⇒The cleaning fee paid by the family = $226. 50 - $187 . 5 = $39
According to question:
Total amount paid = Number of hour x (cost per hour ) + Cleaning fee
Hence, the given equation in slope intercept form is
226.50 = 7.5 ($25) + $39
= volume. So then we need the radius which would be 5. So, 
= about 523.3 cm cubed
