<em><u>Question:</u></em>
Find the sales price of the following item.
A camera originally costing $139.99, marked down $18.50
<em><u>Answer:</u></em>
The sales price of camera is $ 121.49
<em><u>Solution:</u></em>
Given that a camera originally costing $139.99, marked down $18.50
Therefore,
Original cost of camera = $ 139.99
Markdown price of Camera = $ 18.50
We have to find the sales price of camera
Use the following formula:
Sales price = Original cost of camera - Markdown price of Camera
Substituting the values, we get
Sales price = 139.99 - 18.50
Sales price = 121.49
Thus sales price of camera is $ 121.49
