Question

Mrs. Venable ordered packs of diapers from Amazon that cost $9 a piece. The shipping cost for her order is $4. Let “d” represent the number of diapers ordered from Amazon. Write an algebraic expression for the cost of ordering the diapers and find the cost of ordering 4 packs of diapers?

Answer 1

Step-by-step explanation:

cost of 1 diaper = $9

cost of d diaper = $9d

shipping cost = $4

so total cost = 9d+4

d= 4

=> cost = 9(4)+4

=> cost = $40
