1. Renting a bicycle at a local Bike shop costs $30 for the first day and $10 for each additional day. a. Create a chart of values and write an equation to find the total cost, C in terms of the number of days d. b. Use the equation you created in Part a to find the cost of renting a bike for 5 days. SHOW ALL THE WORK PLEASE :)
Equation: C = 10d + 30
The equation would be written with the $30 as a constant. That means that no matter how many days you have the bike, you will pay 30. How many days is the independent variable. y = 30 + (how much per day)(the cost per day).
C=10d + 30
thats the equation correct
yes that is the equation.
okay the value chart?
now you plug in your number of days. Just pick some. Start with one day, which will be your d, and then do the math. y = 30 + 10(1) puts the y at 40. Now do 2 days. y=30 + 10(2) which puts y at 50. Do the same for several days.

in 5 days
so it would be 80 in 5 days
They want you to plug in 5 for d. Do this: Cost = 30 + 10(5). What is the cost for this equation?
yes 80
so thats the value chart up above
yes it is. Do the 4 and the 5. Put them in the d column, then fill in the appropriate cost (y).
thank you both so so much :)
So with each passing day, the price increases by 10. |dw:1412169866186:dw|
