Charles bought 20 papers to draw. Today Charles drew 6 pictures. Yesterday he drew 6 pictures before going to work and some pictures when he came back. How many pictures did Charles draw when he came back from work knowing that he has 2 papers left?

Charles drew 6 + 6 =

<<6+6=12>>12 pictures. He has 20 - 12 = <<20-12=8>>8 papers left. So Charles drew when he came back from work 8 - 2 = <<8-2=6>>6 pictures. #### 6 A cookfire burns three logs every hour. It was built with six logs to start. If it gets two more logs added to it at the end of every hour, how many logs will be left after 3 hours? After 3 hours, it will have 3 * 2 = <<3*2=6>>6 logs added to it. After 3 hours, it will have burned 3 * 3 = <<3*3=9>>9 logs. After 3 hours, the cookfire will have 6 + 6 - 9 = <<6+6-9=3>>3 logs left. #### 3 The difference in age between Declan's elder son and younger son is 10 years. If the elder son is 40 years old now, how old will the younger son be 30 years from now? If the elder son is 40 years old now, the younger son is 40-10 = <<40-10=30>>30 years old. In 30 years from now, the younger son will be 30+30 = <<30+30=60>>60 years old. #### 60 Tony tries to drink more water, so he has been tracking how much water he drinks. Yesterday, he drank 48 ounces of water, which is 4% less than what he drank two days ago. How much water did Tony drink two days ago? Tony drank yesterday 100% - 4% = 96% of what he drank two days ago. Since 96% is 48 ounces, then every 1% is equal to 48/96 = 0.5 ounces of water. So, Tony drank 0.5 x 100 = <<0.5*100=50>>50 ounces two days ago. #### 50 Ral is twice as old as Suri. In 3 years, Suri's current age will be 16. What is Ral's current age? If Suri will be 16 in 3 years, that means she is 16 - 3 = <<16-3=13>>13 years old now. Rai is twice as old as Suri, so she is 2 * 13 = <<2*13=26>>26 years old now. #### 26 Trey is raising money for a new bike that costs $112. He plans to spend the next two weeks selling bracelets for $1 each. On average, how many bracelets does he need to sell each day? He needs to sell 112 bracelets because 112 divided by 1 equals <<112/1=112>>112. He has 14 days to sell bracelets because there are seven days in a week and he has two weeks seven times 2 equals <<7*2=14>>14. He has to sell 8 bracelets a day because 112 divided by 14 equals <<112/14=8>>8. #### 8 In three baseball games this week, eighty people watched the second game while 20 fewer people watched the first game than the second game. Then 15 more people watched the third than the second game. If there were a total of 200 people who watched the games last week, how many more people watched the games this week than last week? This week, 80 - 20 = <<80-20=60>>60 people watched the first game. While 80 + 15 = <<80+15=95>>95 people watched the third game. A total of 80 + 60 + 95 = <<80+60+95=235>>235 people watched the games this week. Thus, 235 - 200 = <<235-200=35>>35 more people watched the games this week than last week. #### 35 If Alice purchased 3600 acorns for nine times the price Bob paid, and Bob paid $6000 for his acorns, how much money did Alice pay for each acorn? Nine times the price Bob paid for his acorns is 9*$6000 = $<<9*6000=54000>>54000 If Alice purchased 3600 acorns for nine times the price Bob paid, she paid $54000/3600 = $15 for each acorn. #### 15 A company is lining a 900-foot path with a fence. Every 6 feet, a fence pole is placed. The entire path is lined with a fence except for a 42-foot bridge. How many fence poles will be placed along the whole path on both sides? There are 900 - 42 = <<900-42=858>>858 feet of path to line. There are poles every 6 feet, so the company needs 858 / 6 = <<858/6=143>>143 poles. The poles have to go on both sides of the path, so there will be 143 * 2 = <<143*2=286>>286 fence poles along the whole path. #### 286 American carmakers produce 5 650 000 cars each year. Then they distribute it to 5 car suppliers. The first supplier receives 1 000 000 cars each. The second supplier receives 500 000 cars more while the third car supplier receives the same number as the first and second suppliers combined. The fourth and the fifth supplier receive an equal number of cars. How many cars do the fourth and fourth suppliers each receive? The second supplier receives 1 000 000 + 500 000 = 1 500 000 cars. The third supplier receives 1 000 000 + 1 500 000 = 2 500 000 cars. So the first to third suppliers receive a total of 1 000 000 + 1 500 000 + 2 500 000 = 5 000 000 cars. Thus, 5 650 000 - 5 000 000 = 650 000 cars are left to be divided by the two other suppliers. Therefore, the fourth and fifth suppliers receive 650 000/2 = 325 000 cars each. #### 325,000
