Question

A nursery owner buys 5 panes of glass to fix some damage to his greenhouse. The 5 panes cost 12.75​$. ​Unfortunately, he breaks 2 more panes while repairing the damage. What is the cost of another 2 panes of​ glass?

Answer 1

$5.10

Explanation:

The owner buys 5 panes of glass for $12.75. So to find the cost of 1, we need to divide the total cost by the amount of planes. In this case, 12.75 divided by 5. This gives you $2.55 per plane. And since he is buying 2 more, we would multiply the cost of the plane (2.55) by the amount we are buying (2). So we do 2.55 X 2 and we get $5.10
