Since the Hargrove’s younger daughter hadn’t taken part in the mathematical deliberations about the candy to purchase, she was selected to go to the store to buy the family’s Halloween candy. Being less mathematically compulsive than the rest of the family, she really couldn’t care less about how many grams of chocolate and nuts are in the candy. She figured she needed to buy at least 90 pieces of candy so she wouldn’t have to share with her brother and sister like last year. She also knew that her father wasn’t going to give her more than $24. When she got to the store, she saw that Twix-or-Tweats came in bags of 20 bars that cost $6 each. Batterfingers came in bags of 15 bars that cost $3 each.
