Answer this plzzzzzzz?
Alex Ar [27]

Answer:

Pretty sure it's $6.45

Step-by-step explanation:

So you need to find how much it costs to fix 1 pane.

For that you divide 17.20/8= 2.15

so to fix 1 pane it costs $2.15

Now you need to find the cost to fix 3 panes. Multiply 2.15x3= 6.45

So to fix another 3 panes he needs to pay $6.45

Hope this helps:)
