Hi Keith,

Sorry I didn't get to this before your homework was due. The idea is to set up use a variable to represent how much of his purchase was electronics and then use that variable to represent the amount that was not electronics as well.

We'll be sure to talk about this problem during the Live Homework Discussion as well!

FYI, the issue is that the dollar sign is used to write math equations (for example if I write 2\times 3 inside dollar signs i get:  $2\times 3$.) So they sometimes cause problems in the forum. You can use \ and then a dollar sign (which is what I used here: \$) to display an actual dollar sign.

Best,

John
