Answer: $133.20
Step-by-step explanation: To simply find the sales tax all you have to do is:
Step 1 Multiply: 120 x .11 = 13.2
Step 2 Add: 120 + 13.2 = 132.2
So Robert actually has to pay $133.20
r=9b_9a =r+9a/9=9b/9=b=r+9a/9
The second part would be $700. I'm not sure how I would solve the first part. You should click the hint button.<span />
