Ryan ordered a wallet for $28.92, a sweater for $35.81 and a watch for $99.24. he added $25.85 for tax, shipping and handling. what was the total cost of ryan's order?

Adding all the items ordered by ryan 
we get ,
     99.24+35.81+28.92= 163.97
     with tax = 163.97+25.85= 189.82

so the total cost of ryan's order was $163.97 without including tax.

You would plot 83 on the 83 line and you would plot -113 on the -113 line.
