Question

The price of a gift plus 14% delivery charge comes to a total cost of $19.38. What was the price of the gift?

Step 1 of 2 : Describe the above situation as a linear equation, using "x" or "y" as variable names to describe the unknown quantity.

Answer 1

1.14x = 19.38

$17

Explanation:

Let the price before delivery charge = x.

The charge is 14%, so it is 14% of x, or 0.14x.

The original price plus charge is x + 0.14x, or 1.14x.

1.14x = 19.38

x = 19.38/1.14

x = 17

The price is $17
