Answer:
611.11$
Explanation:
x=price of the sofa
x+0.08*x=660
1.08*x=660
x=660/1.08=611.11
$712.80
What you want to do first is multiply 0.08 by 660. You should get 52.8, which in money would be $52.80. After that, all you have to do is add $52.80 to $660, and that should get you $712.80. Hope that helped!
