Question 1062001: We are doing linear applications in math. Need help on how to set problem up. Problem: Anita went to the parkway and decided to rent a bicycle. It cost $8 an hour to rent bicycle and $2 for every hour. How much would it cost to go riding for 4 hours? I know you need to label the variable (what you are trying to find), make an equation, and solve.
Thanks for your help

Comment:: I modified your 4th sentence.
----
C(x) = 8 + 2x where x is the number of hours
----
Your Problem:
C(4) = 8 + 2*4 = $16.00

You must have made a mistake in the description. I am giving the intent as cost is $8 to rent a bike and then $2 every hour.
CHOOSE VARIABLES:
y, cost as a dependent variable on the number of hours spent renting the bicycle
m, the PRICE, for renting the bicycle, as DOLLARS per HOUR
x, time in hours of the rental
b, The COST OR PRICE to rent the bicycle just to rent it, not counting any amount of time in hours
-
-
EQUATION FOR COST, DEPENDENT ON x:
-
You CAN make other choices for the variables.
Using the values given in the description:
