Question

The cost to rent skis at a local sporting goods store is $15 plus $20 per day. Which equation models the relationship between the total cost to rent, c, and the length of the rental in days, d?
c = (15 + 20)d
c = 15d + 20
c = 20d + 15
c = (15 + d)20

Answer 1

Answer:

c = 20d +15 is the equation

Answer 2

Answer:

$C= 20d +15$

Step-by-step explanation:

The cost to rent skis at a local sporting goods store is $15 plus $20 per day.

rent per day is $20

Total cost = rent per day times rental days + initial cost

Initial cost is $15, rent per day is $20

Length of rental in days is d  and total cost is c

Replace the variables and values in the equation

So the equation becomes

$C= 20d +15$
