Question

A nursery owner buys 9 panes of glass to fix some damage to her greenhouse. The 9 panes cost

$26.55. Unfortunately, she breaks 4 more panes while repairing the damage. What is the cost of
another 4 panes of glass?

Answer 1

Answer: $11.80 for another 4 panes of glass.

Step-by-step explanation: We know that 9 panes of glass cost $26.55, but we should first find how many dollars would it cost per pane of glass, or 1.

So, we can divide 26.55 by 9 to find the price per 1 pan of glass.

26.55/9 = 2.95, or $2.95 per pane of glass.

Now, we want to know how much it will cost for 4 panes of glass. Simply multiply 2.95 by 4.

2.95 x 4 = 11.8, or $11.80 for another 4 panes of glass.

Answer 2

It will cost 11.80 for the 4 panes

Explanation:

We can use ratios to solve

9 panes 4 panes

--------------- = ----------

26.55 x dollars

Using cross products

9x = 4*26.55

9x =106.20

Divide each side by 9

9x/9 = 106.20/9

x =11.80

It will cost 11.80 for the 4 panes
