Edmund is buying a new computer and needs to save up $75 before he has enough. He convinces his parents to pay him for extra chores. He normally has to do 12 chores a week. His parents agree to pay him $2 for every extra chore he does during the week. If he does 4 chores a day for two weeks, how much does he earn?
Let's think: In two weeks, he has to do 24 chores because 2 x 12 = 24. He now does 28 chores a week because 7 x 4 = 28. He does 56 chores in two weeks because 2 x 28 = 56. He has done 32 extra chores because 56 - 24 = 32. He earns $64 because 2 x 32 = 64.. The answer is: 64.

Bill is trying to control the pests in his garden. Each spider he introduces eats 7 bugs, and each time he sprays the garden he reduces the total bug population to 80% of what it was previously. If the garden has 400 bugs to start, and Bill sprays once and introduces 12 spiders, how many bugs are left?
Let's think: First find the total bug population after spraying: 80% * 400 bugs = 320 bugs. Then find the total number of bugs each spider eats: 12 spiders * 7 bugs / spider = 84 bugs. Then subtract that number from the number of bugs left after spraying to find final number of bugs: 320 bugs - 84 bugs = 236 bugs.. The answer is: 236.

Bridgette and Alex are getting married. Bridgette is inviting 84 guests, and Alex is inviting two thirds of that number of guests. They hired a caterer to make a plated meal for each guest at the wedding reception. The caterer always makes ten extra plates just in case something goes wrong. Each plate of steak and asparagus in garlic butter will have 8 asparagus spears on it. How many asparagus spears will the caterer need in all?
Let's think: Alex is inviting 84 * 2 / 3 = 56 guests. Bridgette and Alex’s guests will need 84 + 56 = 140 plates. The caterer makes 10 extra plates, so they will need 140 + 10 = 150 plates. To put 8 asparagus spears on each plate, the caterer will need 150 * 8 = 1200 asparagus spears.. The answer is: 1200.

The number of visitors that are residents of NYC is 200 / 2 = 100 visitors. The number of NYC resident visitors that are college students is 100 * 0.30 = 30 visitors. The money from the college students that are residents of NYC is 30 * $4 = $120.. The answer is: 120.
