It takes 5 people to lift a car and twice as many people to lift a truck. How many people are needed to lift 6 cars and 3 trucks?

It takes 5 x 2 =

<<5*2=10>>10 people to lift a truck. 5 x 6 = <<5*6=30>>30 people are needed to lift the cars. 10 x 3 = <<10*3=30>>30 people are needed to lift the trucks. Altogether, 30 + 30 = <<30+30=60>>60 people are needed. #### 60 John has to restring 3 basses with 4 strings each, twice as many guitars which have 6 strings each, and 3 fewer 8 string guitars than the normal guitars. How many strings does he need? The basses take 3*4=<<3*4=12>>12 strings He restrings 2*3=<<2*3=6>>6 normal guitars That takes 6*6=<<6*6=36>>36 strings He restrings 6-3=3 guitars with 8 strings So that uses 3*8=<<3*8=24>>24 strings So he uses 12+36+24=<<12+36+24=72>>72 strings #### 72 Annie went to a liquidation sale and bought 5 televisions that each cost $50. She also purchased 10 figurines. If Annie spent $260 in total, how much did a single figurine cost in dollars? Annie spent 5 * $50 = $<<5*50=250>>250 on televisions. She has $260 - $250 = $<<260-250=10>>10 left for the 10 figurines. A single figurine costs $10/10=$1. #### 1 Steven has 4 times as many shirts as Andrew. Andrew has 6 times as many shirts as Brian. If Brian has 3 shirts, how many does Steven have? Andrew has 6 * 3 = <<6*3=18>>18 shirts. So, Steven has 4 * 18 = <<4*18=72>>72 shirts. #### 72 Farmer Randy has 1700 acres of cotton he needs to have planted in 5 days. With a crew of 2 tractors working for 2 days and then a crew of 7 tractors working for another 3 days, how many acres of cotton per day does each tractor need to plant to meet their planting deadline? With 2 tractor teams working for 2 days, this is like 2*2=<<2*2=4>>4 days worth of work by a single tractor, which they call tractor days. With 5 tractor teams working for 4 days, this is 7*3=21 tractor days. In total, the effort of all the tractor teams is 4+21=<<4+21=25>>25 tractor days. If they need to plant 1700 acres with their 25 tractor days, then each tractor team needs to plant 1700/25 = <<1700/25=68>>68 acres of cotton per day. #### 68 Alma is taking a walk and comes across four goats standing behind a fence. Alma has a bag of baby carrots she brought to have for a snack and decides to feed the goats with them. Alma wants to make sure all the goats get the same amount of carrots, so she starts counting them out. She has 47 baby carrots. If she wants to give the exact same amount of carrots to each goat and wants to feed them all the carrots she can, how many will she have left over? Alma has 47 baby carrots to feed 3 goats, 47 / 4 = <<47/4=11.75>>11.75 baby carrots. If she takes away the remaining .75, each goat gets an even 11 carrots each. If Alma feeds 11 carrots to each of 4 goats, that's a total of 11 * 4 = <<11*4=44>>44 carrots Alma feeds the goats. She started with 47 baby carrots - 44 she feeds the goats = <<47-44=3>>3 baby carrots left over. #### 3 The cost of building a certain house in an area is 100,000 more than the construction cost of each of the houses in the area. But it sells for 1.5 times as much as the other houses, which sell at $320,000 each. How much more profit is made by spending the extra money to build? The house cost 320,000*1.5=$<<320000*1.5=480000>>480,000 So it is worth 480,000-320,000=$<<480000-320000=160000>>160,000 more than other houses So the profit is 160,000-100,000=$<<160000-100000=60000>>60,000 more #### 60,000 Asha has to buy some gifts but has no money. She decides to borrow $20 from her brother, $40 from her father, $30 from her mother and is gifted $70 by her granny. She adds this to her savings of $100 and goes out to Target to get what she wanted. If she spent 3/4 of the money, how much money did she remain with? With the amount borrowed from her family, she has a total of 20+40+30= <<20+40+30=90>>90 dollars. With the amount gifted from her granny, she has 70+90 = <<70+90=160>>160 dollars. She adds this to her savings, ending up with a total of 160+100 = <<160+100=260>>260 dollars. She spends 3/4 of this money, which is 3/4*260 = <<3/4*260=195>>195 dollars. The total she remains with is 260-195 = <<260-195=65>>65 dollars #### 65 Greta received 10 more letters in the mail than her brother. Greta's mother received twice the total number of letters Greta and her brother received. Calculate the total number of letters the three received if Greta's brother received 40 letters. Since Greta's brother received 40 letters, Greta received 40+10 = <<40+10=50>>50 letters. Together, Greta and her brother received 50 + 40 = <<50+40=90>>90 letters. Greta's mother received twice the total number of letters Greta and her brother received, which totals 90*2 = <<90*2=180>>180 letters. In total, the three received 90+180 = <<90+180=270>>270 letters. #### 270 Josette bought 3 bottles of mineral water for €1.50. How much will four bottles cost?
