Final answer:
Mr. Jordan sold the camera for $157.50, by calculating 90% of the original $175 cost.
Step-by-step explanation:
To determine the selling price of the camera, which Mr. Jordan sold for 90% of its cost, we can calculate it by finding 90% of the purchase cost.
Let cost = $175
The selling price can be calculated as follows:
Selling Price = Cost * 90/100
Substitute the given cost:
Selling Price = $175 * 90/100
Now, compute the value:
Selling Price = $175 * 0.9 = $157.50
Therefore, Mr. Jordan sold the camera for $157.50.
