Q: Lionel went to the grocery store and bought 14 boxes of Graham crackers and 15 packets of Oreos. To make an Oreo cheesecake, Lionel needs 2 boxes of Graham crackers and 3 packets of Oreos. After making the maximum number of Oreo cheesecakes he can with the ingredients he bought, how many boxes of Graham crackers would he have left over?
A: Lionel has enough Graham crackers to make 14 / 2 = 7 Oreo cheesecakes. Lionel has enough Oreos to make 15 / 3 = 5 Oreo cheesecakes. Therefore, the maximum number of cheesecakes Lionel can make is 5. Lionel needs 2 * 5 = 10 boxes of Graham crackers to make 4 cheesecakes. He'll have 14 - 10 = 4 boxes left over. The answer is 4.

Q: Carla's order at Mcdonald's costs $7.50, but she has a coupon for $2.50. If she gets an additional 20% discount for being a senior citizen, how much does she pay for her order in dollars total?
A: First subtract the coupon amount from the price of the food: $7.50 - $2.50 = $5.00. Then subtract 20% from 100% to find out what percentage of the reduced price Carla pays: 100% - 20% = 80%. Now multiply the price after the coupon by the percentage Carla pays to find the final price: $5.00 * .8 = $4.00. The answer is 4.

Q: A garden is filled with 105 flowers of various colors. There are twice as many red flowers as orange. There are five fewer yellow flowers than red. If there are 10 orange flowers, how many pink and purple flowers are there if they have the same amount and there are no other colors?
A:
The number of red flowers is twice as many as orange so 2 * 10 orange = 20 red flowers. The number of yellow flowers is 5 less than red so 20 red - 5 = 15 yellow flowers. The number of red, orange and yellow flowers is 20 red + 10 orange + 15 yellow = 45 flowers. The number of pink and purple flowers total is 105 flowers total - 45 flowers that are not pink or purple = 60 flowers. The number of pink and purple flowers each is 60 flowers / 2 = 30 flowers each. The answer is 30.
