Answer 1

Hello!

If a nursery owner buys 8 panes of glass to fix some damage to her greenhouse and 8 panes cost a total of $20.40, the total cost of another 3 panes of glass would be $7.65

Explanation:

`20.40` ÷
`8=2.55`

`2.55` ×
`3=7.65`

Hope this helps!

Answer 2

$7.65

Explanation:

First lets find the cost of each window pane:

20.40 / 8 = 2.55

So, each window pane costs $2.55.

Since she broke 3 of the window panes, we will have to multiply the cost of each window by 3:

2.55 x 3 = 7.65

So, she will have to pay $7.65 to replace the three more damages window panes.
