Lighters cost $1.75 each at the gas station, or $5.00 per pack of twelve on Amazon. How much would Amanda save by buying 24 lighters online instead of at the gas station?
Let's think: First find how many packs Amanda would have to buy on Amazon: 24 lighters / 12 lighters / pack = 2 packs. Then multiply that number by the cost per pack to find the total cost from Amazon: 2 packs * $5 / pack = $10. Then multiply the total number of lighters Amanda buys by the cost per lighter at the gas station: 24 lighters * $1.75 / lighter = $42. Then subtract the total Amazon cost from the total gas station cost to find the savings: $42 - $10 = $32.. The answer is: 32.

The bakery made 95 muffins. They will be packed in boxes with 5 muffins in each box. If there are only 10 available boxes, how many boxes do they still need to pack all the muffins?
Let's think: A total of 10 x 5 = 50 muffins will be packed in 10 boxes. So 95 - 50 = 45 muffins still need to be packed in the boxes. Thus, 45 / 5 = 9 boxes are still needed to pack all those 45 muffins.. The answer is: 9.

Peter needs to buy birdseed to last a week. He knows that each parakeet eats 2 grams a day. His parrots eat 14 grams a day. His finches eat half of what a parakeet eats. If he has 3 parakeets, 2 parrots and 4 finches, how many grams of birdseed does he need to buy?
Let's think: His parakeets eat 6 grams a day, because three parakeets times two grams each equals 6 grams. His parrots will eat 28 grams a day because two parrots times 14 grams equals 28 grams. Each finch will eat 1 gram a day, because they eat half of what a parakeet does and 1 / 2 of 2 equals one. His finches will eat 4 grams a day because four finches times 1 gram equals 4 grams. His birds eat 38 grams a day because 6 plus 28 plus 4 equals 38. Each week has 7 days. Therefore, in a week he will need 266 grams because 7 times 38 equals 266.. The answer is: 266.

Florida is starting a promotion where every car that arrives gets one orange per passenger. A family of 4 arrives and gets their oranges. They had planned to stop for a snack later where they would spend $15 in total, but now that they have the oranges they don't have to buy them at the stop. When they get to the stop they see that the oranges would've cost $1.5 each. What percentage of the money they planned to spend did they save instead?
Let's think:
The oranges would've cost $6 because 4 x 1.5 = 6. The proportion of their original spending plan was .4 because 6 / 15 = .4. They saved 40% of the money they planned to spend because .4 x 100 = 40.. The answer is: 40.
