If Abigail spent $4.59 on a sandwich, $65.98 on a i-pod, $1,000.50 on a wide screen TV, $60.00 on a new i-phone, how much did she spend?

 I think you might just be having trouble lining up the decimals...

Just do this

          4.59

+      65.98

+  1000.50

+      60.00

--------------

Now....just add down the columns as you normally would....!!!

You had trouble adding the numbers. Add it like you add normaly!!!                                                                                  

Easy as that.
