Bennett sells window screens. He sold twice as many window screens in February as he sold last month. In February, Bennett sold a fourth of what he sold in March. If Bennet sold 8800 window screens in March, how many screens did Bennett sell from January to March?

In February, Bennett sold 8800/4 =

<<8800/4=2200>>2200 window screens. In January, Bennett sold 2200/2 = <<2200/2=1100>>1100 window screens. Between January and March, Bennett sold 8800+2200+1100 = <<8800+2200+1100=12100>>12100 window screens. #### 12100 Randolph is 5 years older than Sydney. Sydney is twice as old as Sherry. If Sherry is 25, how old is Randolph? Sydney is 25*2 = <<25*2=50>>50 years old. Randolph is 50+5 = <<50+5=55>>55 years old. #### 55 Pauline has 125 matchbox cars. They are all either convertibles, trucks, regular cars. 64% of them are regular cars. 8% are trucks. How many convertibles does she own? The trucks and regular cars make up 72% of her collection because 64+8 equals <<64+8=72>>72 This means convertibles make up 28% of her collection because 100-72 equals 28. She has 35 convertibles because 125 times .28 equals <<125*.28=35>>35 #### 35 At least a third of Fred's marbles are dark blue. All of the rest are red, except for 4 that are green. If he has 63 marbles, how many of them are red? Fred has 63/3 = <<63/3=21>>21 dark blue marbles. Fred has 63-21 = <<63-21=42>>42 red and green marbles. Fred has 42-4 = <<42-4=38>>38 red marbles. #### 38 Joshua, Jose, and Albert are collecting rocks. Joshua collected 80 rocks while Jose collected 14 fewer rocks. Albert has collected 20 more rocks than Jose. How many more rocks did Albert collect than Joshua? Jose collected 80 - 14 = <<80-14=66>>66 rocks. Albert collected 66 + 20 = <<66+20=86>>86 rocks. Thus, Albert collected 86 - 80 = <<86-80=6>>6 more rocks than Joshua. #### 6 Delta, Beta and Gamma decided to share 40 donuts. Delta took 8 donuts and Beta took three times as many as Gamma. How many donuts did Gamma receive? Let x = the number of donuts Gamma took. The total donuts Gamma and Beta have is 40 - 8 = <<40-8=32>>32 donuts. 3x is the number of donuts for Beta. 3x + x is the number of total donuts for Beta and Gamma. If we add the two x terms, we get 4x = 32. If we divide both sides by 4, we get x = 8, so Gamma has 8 donuts. #### 8 Marta is weighing fruit at the grocery store. The apples weigh four ounces each and the oranges weight 3 ounces. Each plastic bag in the grocery store can hold 49 ounces of fruit before it splits. If Martha wants to put an equal number of apples and oranges in each bag, and she wants to buy 3 full bags of fruit, how many ounces of apples should she buy? First figure out how many ounces of fruit fit in three bags by multiplying the number of bags by the number of ounces per bag: 49 oz/bag * 3 bags = <<49*3=147>>147 oz Since Marta wants the same number of apples and oranges in each bag, we know the fruits always come in pairs. Find the weight of each pair of fruit by adding the weight of one apple to the weight of one orange: 3 oz + 4 oz = <<3+4=7>>7oz Now figure out how many pairs of fruit Marta needs to fill the bags by dividing the total weight in the bags by the weight of each pair of fruit: 147 oz / 7 oz = <<147/7=21>>21 Now multiply the number of apples Marta needs to buy (21) by the weight per apple (4 oz) to find how many ounces she should buy: 21 * 4 oz = <<21*4=84>>84 oz #### 84 Michael was watching a TV show, which was aired for 1.5 hours. During this time, there were 3 commercials, which lasted 10 minutes each. How long (in hours) was the TV show itself, not counting commercials? Each commercial lasted 10 minutes, so three commercials lasted 3 * 10 = <<10*3=30>>30 minutes. The show was aired for 1.5 hours, and 30 minutes is 0.5 of an hour, so without the commercials, the show was 1.5 - 0.5 = <<1.5-0.5=1>>1 hour long. #### 1 Mr. Dubois buys a new car for $13,380. He pays $5,400 and pays the rest by giving $420 a month. In how many months will the car be fully paid for? Dubois has to pay $13,380 – $5,400 = $<<13380-5400=7980>>7,980 more. He will pay that in $7,980 : $420 = 19 months. #### 19 Maddox and Theo both bought 3 Polaroid Cameras, each sold at $20 per camera from Amazon, and decided to sell them on eBay. Maddox sold his cameras at $28 each, while Theo sold his cameras at $23 each. How much more profit did Maddox get from the sale of his cameras than Theo? The total cost of buying 3 cameras from Amazon for both Maddox and Theo was 3*$20=$<<3*20=60>>60 Maddox sold his cameras at $28 each, for a total of $28*3=$<<28*3=84>>84 Maddox made a profit of $84-$60=$<<84-60=24>>24 from the sale of his cameras. Theo sold his cameras on eBay for $23*3=$<<23*3=69>>69 Theo made a profit of $69-$60=$<<69-60=9>>9 Maddox made $24-$9=$15 more profit than Theo from the sale of his cameras. #### 15
