Answer :
Function defining the cost of buying and shipping will be represented by,
C(x) = ax + b
Here, a = price of one jar, b = shipping charges and x is the price of jar preserve
Function representing the cost C for buying and shipping 'x' jars of preserves will be,
C = $(9.15x + 3.75)
It's given in the question,
- Homespun Jellies charges $8.50 for each jar of preserves.
Let the number of jars purchased = x
Therefore, charges for 'x' jars = $8.50x
- Shipping and handling charges for each order = $3.75 plus $0.65 per jar
So the shipping and handling charges for shipping 'x' jars = $(3.75 + 0.65x)
Therefore, total charges for shipping and preserving 'x' jars = $(3.75 + 0.65x) + $8.50x
Therefore, function representing the cost C for buying and shipping 'x' jars of preserves will be,
C = $(3.75 + 0.65x) + $8.50x
C = $(9.15x + 3.75)
