3. Amanda is buying presents for her teacher.

She finds a jar of purple spotted grasshoppers for $195 and…

a wig made of genuine cobra teeth for $123.

She wants to add the two prices together (195 + 123).

She knows she needs a friendly number so she can do the work in her head.

She decides to change 195 to 200 by adding 5.

She is not sure what to do with the other number (does she add 5 or take 5 away?)

She thinks she should add 5 as well (123 + 5 = 128).

Therefore she adds 200 + 128 and gets 328.

Is she correct? Explain why or why not.
