Maya loves to read books. Last week she read 5 books. Each book had 300 pages of text. This week she read twice as much. How many pages did Maya read in total?

How many pages did Maya read last week? ** Last week Maya read 5 * 300 =

<<5*300=1500>>1500 pages of text. How many pages did Maya read this week? ** This week she doubled the result, so she read 2 * 1500 = <<2*1500=3000>>3000 pages. How many pages did Maya read in total? ** In total Maya read 1500 + 3000 = <<1500+3000=4500>>4500 pages of text. #### 4500 Emma is 7 years old. If her sister is 9 years older than her, how old will Emma be when her sister is 56? How old is Emma’s sister? ** Emma’s sister is 7 + 9 = <<7+9=16>>16 years old. How old will Emma’s sister be when Emma is 40? ** In this many years, Emma’s sister will be 56 years old: 56 - 16 = <<56-16=40>>40 years. How old will Emma be when her sister is 56? ** When her sister is 56 years old, Emma will be 7 + 40 = <<7+40=47>>47 years. #### 47 On their way driving to Los Angeles, Benjamin and James see lots of billboard ads. Curious, Benjamin starts to count how many they see. In the first hour once he starts counting he counts 17 billboards. In the second hour once he starts counting he sees 20 billboards. In the third hour he sees 23 billboards. James asks Benjamin the average number of billboards they've seen per hour. What should Benjamin tell him? How many billboards does Benjamin count? ** Benjamin counts 17 + 20 + 23 = <<17+20+23=60>>60 billboards total on the way to Los Angeles. What is the average number of billboards they saw per hour? ** Benjamin saw those billboards over 3 hours, so the average number of billboards per hour they saw 60 / 3 = <<60/3=20>>20 billboards per hour. #### 20 Milo can roll downhill on his skateboard at twice the speed that he can run. And Milo's best friend, Cory, can drive his wheelchair at twice the speed that Milo can roll downhill on his skateboard. If Cory always drives his wheelchair at 12 miles per hour, how many miles can Milo run in two hours? How fast does Milo roll downhill on his skateboard? ** Since Cory drives his wheelchair at 12 miles per hour, then Milo rolls downhill on his skateboard at 12/2 = <<12/2=6>>6 miles per hour. How fast does Milo run? ** Therefore, Milo runs at 6/2 = <<6/2=3>>3 miles per hour. How many miles will Milo travel in 2 hours? ** If Milo runs for 2 hours at 3 miles per hour, then Milo will travel 2 * 3 = <<2*3=6>>6 miles. #### 6 A bird eats 7 berries a day. Samuel has 5 birds. How many berries do Samuel's birds eat in 4 days? How many berries does a bird eat in 4 days? ** A bird eats 7 x 4 = <<7*4=28>>28 berries in 4 days. How many berries do Samuel's birds eat in 4 days? ** So, 5 birds can eat 28 x 5 = <<28*5=140>>140 berries in 4 days. #### 140 A banana tree has 100 bananas left after Raj cut some bananas from it. If Raj has eaten 70 bananas and has twice as many remaining in his basket, how many bananas were on the tree initially? How many bananas does Raj have left? ** If Raj has eaten 70 bananas in the basket, he has 2*70 = <<70*2=140>>140 bananas. How many bananas did Raj cut from the tree? ** The total number of bananas that Raj cut from the tree is 140+70 = <<140+70=210>>210 How many bananas were on the tree initially? ** On the tree initially were 100+210 =<<100+210=310>>310 bananas. #### 310 Jim spends 8 hours scuba diving. In that time he finds a treasure chest with 100 gold coins in it. He also finds 2 smaller bags that have half as much gold each. How much gold does he find per hour? How many gold coins are in each smaller bag? ** The smaller bags each have 100/2=<<100/2=50>>50 gold coins each How many gold coins are in total? ** So in total, they have 50*2=<<50*2=100>>100 coins How many gold coins did Jim find? ** So he found 100+100=<<100+100=200>>200 coins How many gold coins does Jim find per hour? ** So he finds 200/8=<<200/8=25>>25 coins an hour #### 25 Tom fills a 250 pound sandbag 80% full. But the filling material he is using is 40% heavier than sand. How much does the bag weigh? How much does the bag weigh when it is full of sand? ** The bag full of sand would weigh 250 * .8 = <<250*.8=200>>200 pounds How much does the bag weigh when it is full of filling material? ** The filling material would make it 200 * .4 = <<200*.4=80>>80 pounds heavier How much does the bag weigh? ** So it weighs 200 + 80 = <<200+80=280>>280 pounds #### 280 Michael wants to dig a hole 400 feet less deep than twice the depth of the hole that his father dug. The father dug a hole at a rate of 4 feet per hour. If the father took 400 hours to dig his hole, how many hours will it take for Michael to dig a hole that is 400 feet less than twice as deep as his father's hole working at the same rate? How deep was the father's hole? ** Since the father dug a hole with a rate of 4 feet per hour, if the father took 400 hours digging the hole, he dug a hole 4*400 = <<4*400=1600>>1600 feet deep. How deep is the hole that Michael's father dug? ** Twice the depth of the hole that Michael's father dug is 2*1600 = <<2*1600=3200>>3200 feet How deep does Michael want to dig? ** Michael wants to dig a hole 400 feet less than twice the depth of the hole that his father dug, meaning he wants to dig a hole 3200-400 = 2800 feet deep. How many hours will it take Michael to dig a hole that is 400 feet less than twice as deep as his father's hole working at the same rate? ** To dig a hole that is 400 feet less than twice as deep as his father's hole working at a rate of 4 feet per hour, Michael will have to work for 2800/4 = 700 hours. #### 700 At the Sterling Auto Store, they have 500 cars for sale. If they have 10 sales professionals, and each salesperson sells 10 cars per month, how many months will it take for them to sell all of the cars? How many cars do the sales professionals sell in a month? ** If 10 sales professionals each sell 10 cars per month, then they sell a combined 10*10=<<10*10=100>>100 cars per month. How many months will it take the sales team to sell all of the cars? ** If the store has 500 cars, then it will take the sales team 500/100=<<500/100=5>>5 months to sell all of the cars. #### 5
