Third Grade: Kylie's mother said if she read five new books this week that she would take her and a friend to Starbuck's after school on Friday for a treat of their choice. She successfully read the five books plus an additional two. On the way to Starbuck's her mother told the two girls that she was going to stop to top off the gas tank and that the girls could split the remainder of the $20 on treats. Kylie was hoping to get a grande hot chocolate that cost $2.50 and a cheese danish that cost $2.45. Her friend wanted to get a grande strawberries and crème frappuccino that cost $4.45. If gas cost $2.91 per gallon and it took three gallons to fill up the tank, do the girls have enough money for their desired treats? How much money was left over or how much more would they need?
