Answer:

B. $79 + 0.1($79)

Step-by-step explanation:

Given that;

the shipping cost for an order = 1/10 multiply by the cost of the items bought;

i.e. $\dfrac{1}{10}\times x$

where

x = cost of items ordered for.

This implies that:

$\implies$ x + 0.1x

The objective is to determine the expression for the total cost of an order which is $79

x = 79

Then, the total cost of an order is

$79 + 0.1($79)
