Answer:
For the cost to be the same the a person have to rent billy's and Lisa's 20 times.
Explanation:
Billy's rentals charges a yearly fee of $105 and $9.50 each time a member wants to rent a boat. The total cost can be represented as follows.
where
x = number of times each member rents a boat
y = total cost
y = 105 + 9.50x
Lisa boat rental does not charge a yearly fee but charges $14.75 every time a member rents a boat.
y = 14.75x
For the cost to be the same
105 + 9.50x = 14.75x
collect like terms
105 = 14.75x - 9.50x
105 = 5.25x
divide both sides by 5.25
x = 105/5.25
x = 20
