Answer:
[tex]\boxed{$12.60}[/tex][tex]\boxed{12.60}[/tex]
Step-by-step explanation:
Hey there!
Given
5 light bulbs = $9
__________________________________________________________
9 ÷ 5 = 1.8
Each light bulb is 1.8
To check do 1.8 • 5 = 9
Now we have cost per light bulb, do
7 • 1.8
= $12.6 for 7 light bulbs
Hope this helps :)
