A furniture store delivers for $40 plus $0.75 for every mile they have to travel from the store. Which function represents the cost for delivery, c(m), given the distance from the store, m, in miles, and how much does delivery cost for someone who lives 60 miles from the store?
A. c(m) = 40 + m
$80.00
B. c(m) = 40.75 + m
$100.75
C. c(m) = 40 + 0.75m
$85.00
D. c(m) = 40.75 + 0.75m
$90.75
The correct function that represents the cost for delivery, c(m), given the distance from the store, m, in miles is option D: c(m) = 40.75 + 0.75m.
To find out how much delivery would cost for someone who lives 60 miles from the store, we can substitute m = 60 into the function:
c(60) = 40.75 + 0.75(60)
c(60) = 40.75 + 45
c(60) = $85.75
Therefore, the delivery cost for someone who lives 60 miles from the store is $85.75.
