Mr. Smith has incurred a 2% finance charge because he was not able to pay on time for his balance worth $150. If he plans to settle his balance today, how much will Mr. Smith pay?

The finance charge amounts to $150 x 2/100 = $

<<150*2/100=3>>3. Thus, Mr. Smith will pay a total of $150 + $3 = $<<150+3=153>>153. #### 153 Happy Island has 60 turtles. This means there are 10 more than 2 times as many turtles on Happy Island as on Lonely Island. How many turtles are there on Lonely Island? After subtracting 10 from the number of turtles on Happy Island, we get 60 - 10 = <<60-10=50>>50 turtles Dividing this number by two, we find that the number of turtles on Lonely Island is 50/2=<<50/2=25>>25 turtles. #### 25 If Jason eats three potatoes in 20 minutes, how long, in hours, would it take for him to eat all 27 potatoes cooked by his wife? Since 1 hour is 60 minutes, 20 minutes is 20/60=1/3 of an hour. Eating 3 potatoes per 20 minutes is 3/(1/3)=<<3/(1/3)=9>>9 potatoes per hour. At 9 potatoes per hour, it will take Jason 27/9=3 hours to eat all of the potatoes. #### 3 Sam has 18 cows. 5 more than half the cows are black. How many cows are not black? Half of the cows: 18/2=<<18/2=9>>9 Black cows: 5+9=<<5+9=14>>14 18-14=<<18-14=4>>4 cows #### 4 John decides to fix a racecar. It cost $20,000 to fix but he gets a 20% discount. He wins his first race but only keeps 90% of the money. The prize is $70,000. How much money did he make from the car? He gets a 20000*.2=$<<20000*.2=4000>>4000 discount So he paid 20000-4000=$<<20000-4000=16000>>16000 He kept 70000*.9=$<<70000*.9=63000>>63000 So he made 63,000-16,000=$<<63000-16000=47000>>47,000 #### 47,000 John climbs up 9 flights of stairs. Each flight is 10 feet. If each step is 18 inches, how many steps does he climb up? He has to climb 9*10=<<9*10=90>>90 feet That means he needs to climb 90*12=<<90*12=1080>>1080 inches That means he needs to climb 1080/18=<<1080/18=60>>60 stairs #### 60 Madeline has $48 and her brother has half as much. How much do they have together? Madeline's brother has $48/2 = $<<48/2=24>>24. Together, they have $48 + $24 = $<<48+24=72>>72. #### 72 Hank is raising money for the local homeless shelter. Hank makes $100 in a carwash and donates 90% of the proceeds to the local homeless shelter. Hank makes $80 in a bake sale and donates 75% of the proceeds to the local homeless shelter. Then he makes $50 mowing lawns and donates 100% of the proceeds to the local homeless shelter. How much money does Hank donate in total? From the carwash, Hank donates $100 * 0.90 = $<<100*0.90=90>>90 From the bake sale, Hank donates $80 * 0.75 = $<<80*0.75=60>>60 From mowing lawns, Hank donates $50 * 1.00 = $<<50*1=50>>50 Hank donates a total of $90 + $60 + $50 = $<<90+60+50=200>>200 #### 200 A local farm is famous for having lots of double yolks in their eggs. One carton of 12 eggs had five eggs with double yolks. How many yolks were in the whole carton? The carton had 12 - 5 = <<12-5=7>>7 eggs with one yolk. It had 5 eggs with double yolks, which added * 2 = <<5*2=10>>10 yolks. Thus, there were 7 + 10 = <<7+10=17>>17 yolks in the whole carton. #### 17 Chloe and Max played Mario Kart together. The ratio of Chloe’s wins to Max’s wins is 8:3. Chloe won 24 times. How many times did Max win? We are trying to figure out how many times Max won at Mario Kart, so we'll call that number Y. We know the ratio of Chloe’s wins to Max’s wins is 8/3, so 8/3 = 24/Y. Next, we will multiply to find the cross-products. 8 x Y = 3 x 24 or 8Y = 72. We want to get figure out Y, so we need to get it by itself by dividing by 8, like this: 8Y / 8 = 72 / 8. Y = <<9=9>>9, so Max won 9 times. #### 9
