Thread: Renting a bicycle at a local Bike shop costs $30 for the first day and $10 for

each additional day. ? Create a chart of values and write an equation to find the total cost, C in terms of the number of days d.
Use the equation you created in part a to find the cost of renting a bike for 5 days

this is so easy
first of all the equation is

C = 30 + 10d

because 30 is a one time payment and 10d is how much it costs for each day you rent the bike.

to do the chart of values, just do

d | C
_____

1 | 40
2 | 50
3 | 60
4 | 70
5 | 80

jus substitute in each numerical value for "d" into the equation to get your C


and just subsitute in 5 for d and you should get

C = 30 + 10(5)

C= 30 + 50

C=80 and that's your final answer
