Question

I need to know to see if my answer is correct more so I can study from what mistakes I made 

 

Answer 1

If we had a sale price of 30% off of $1,050

then the sale price is 70% of $1,050 or 0.7(1050)

 

Then we add 7% sales tax to that making the

final price paid 107% of [0.7(1050)] ...

 

1.07[0.7(1050)] = $786.45
