Question: Chad is hosting a BBQ on the hottest day of the year, where there will be a total of 15 people. He will need 2 pounds of ice per person to account for the heat. One pound bags of ice are sold for $3.00 for a pack of 10. How much will he spend on ice?
Answer: He’s inviting 15 guests and will need 2 pounds per person so he will need 15 * 2 = 30 pounds of ice. Ice is sold in 10 - pound bags and he needs 30 pounds so he will need 30 / 10 = 3 bags of ice. Each bag is $3.00 and he needs 3 bags so they will cost 3 * 3 = $9.00. The answer is 9.

Question: Tom Sawyer has tricked his friends into whitewashing Aunt Polly's 100-foot fence. His first friend, Ben, whitewashed 10 feet. His second friend Billy whitewashed a fifth of the remaining fence. A third friend, Johnny, whitewashed a third of the fence that was left after that. How much of the fence still needs to be whitewashed?
Answer: It's a 100 - foot fence, and Ben whitewashed 10 feet, so there are 100 - 10 = 90 feet left after Ben is done. Billy whitewashed a fifth of that, or 90 / 5 = 18 feet. There is now 90 - 18 = 72 feet of fence left. Johnny whitewashes a third of that, or 72 / 3 = 24 feet. That leaves 72 - 24 = 48 feet of fence left to be whitewashed. The answer is 48.

Question: Jim is baking loaves of bread. He has 200g of flour in the cupboard, 100g of flour on the kitchen counter, and 100g in the pantry. If one loaf of bread requires 200g of flour, how many loaves can Jim bake?
Answer:
Altogether, Jim has 200g + 100g + 100g = 400g of flour. He can therefore bake 400g / 200g = 2 loaves of bread. The answer is 2.
