Best ResponseYou've already chosen the best response.1first you figure out how many calories there are total; in Mac and Cheese you've got 50 grams, with 4 calories per (since they're equal, we don't worry about separating them) so that's 200 calories total. Now we have 40 grams of carbos with 4 calories per gram, for 160 grams altogether. 160 over 200 is .8. Move the decimal to the right two slots and you get a clean 80 percent :) You can figure out the other problem from that, yeah?
