Today each cookie costs $0.75 less than the normal price. Right now if you buy 7 of them it will only cost you $2.80.

1 answer:

5 0

The normal price would be 79 cents, and I can tell you why. First, you divide 2.80 by 7, and you get 0.4, but that's crazy! Why would a cookie cost 4 cents!? So, you have to add the 75 cents, the sale. The answer is 79 cents. Hope I helped! :D
