From the calculation done below, it can be seen that the cost of one orange is 85 cents.
<h3>How do we determine the cost of a product?</h3>
The cost of one orange can be determined as follows:
One dime = 10 cents
2 dollars = 200 cents
Total amount given by Sue to the store clerk = One dime + 2 dollars = 10 cents + 200 cents = 210 cents
Cost of two oranges = Total amount given by Sue to the store clerk –
Change = 210 cents – 40 cents = 170 cents
