Barbara orders her groceries from a store that charges $15 plus the cost of her groceries to deliver her groceries to her home.
crimeas [40]

Answer:

The correct answer is Total Cost Payable = $Exp + $15, where $Exp is the total price of the groceries bought by Barbara

Step-by-step explanation:

Barbara orders her groceries. Let us consider that she orders groceries worth $Exp from a store.

Extra charges levied by the store for delivering the groceries to Barbara's house is $15.

Thus the total payable charge by Barbara for her groceries should include the total price of the groceries and the delivery charges levied by the store.

Thus the Total Cost Payable by Barbara is the sum of the total expenditure by her on the groceries and the delivery charge.

∴ The total cost payable = $Exp + $15.
