Question

Shalika bought a purse for $120. The tax rate is 9%.

What is the total amount Shalika paid?

Answer 1

120/x=100/9 is the awnser i believe

Answer 2

9/100 = x/120
the cross multiply to get:

100x = 1080
divide I080 by 100 to get 10.8

Finally add a 10.8 to 120 ( the original amount) to get $130.80
