1 answer

The cost per box of donuts is the coefficient of d in the function C(d). In this case, the cost per box of donuts is $8.

The flat rate shipping charge is the constant term in the function C(d). In this case, the flat rate shipping charge is $2.

To find the total cost to order 3 boxes of donuts, we substitute d = 3 into the function C(d) and simplify:
C(3) = 8(3) + 2 = 24 + 2 = $26.

Therefore, the total cost to order 3 boxes of donuts is $26.
