The Park Commission proposed the following rate increases for bike rentals
Proposed Bike Rental Rate Increase
-------------------Current Rate------------Increased Rate
Initial Charge---------$6 ------------------$10
Hourly Rate-----------$4--------------------$5
a. Write a variable expression showing the total cost to rent a bike at the current rate. Write a variable expression showing the total cost to rent a bike at the increased rate. Define the variable.
b. Use the variable expressions to calculate the cost to rent a bike for 6 hours at the current rate and at the increased rate. Show all your work.
c. Calculate the percent increase in the total cost to rent a bike for 6 hours if the proposed rates are approved. Show all your work.
d. Jerome paid $42 for a bike rental at the current rate. Write and solve an equation to determine the number of hours he rented the bike. Show all your work.
Thanks in advanced

a) current = total= 6 +4x
increased = total= 10 +5x
b) use x=6 in both my equations up there in part a
c) so take the answer get in part b for the increased rate and subtract the answer in part b for current rate. Then divide this number by the current 6 hour one. Then multiply this number by 100. Thats the percentage.
d)6+4x=42
4x=36
x=9
9 hours
Sorry I didnt have a calculator but those should do.
