The cost of having a package delivered has a base fee of $9.70. Every pound over 5 lbs cost an additional $0.46 per pound. Write
a linear model that represents the cost, C, for the total weight, w, in pounds of the package. Assume 5 lbs. a.
C = 9.7w + 0.46
c.
C = 0.46w + 9.7
b.
C = 0.46w + 12
d.
C = 0.46(w - 5) + 9.7
We are given that the delivery cost of any package has a fixed value of 9.7$ and an additional value for every 5 lbs extra weight and the additionalvalue is given to be 0.46.
The equation for total cost C for given total weight w can be written by
sum of fixed value and every 5 extra lbs
which can be represented by the equation
C= 0.46(w-5) + 97.
Hence, this represents a linearmodel for the given data.
