Alberto spent $2457 on a new engine for his car. Samara spent $25 on oil, $467 on tires and $79 on detailing for her car. How many more dollars did Alberto spend on his car?

Samara = 25 + 467 + 79 = $

<<25+467+79=571>>571 2457 - 571 = $<<2457-571=1886>>1886 Alberto spent $<<1886=1886>>1886 more on his car. #### 1886 The sewers in Middleton can handle 240,000 gallons of run-off. Each hour of rain produces 1000 gallons of runoff. How many days of rain can the sewers handle before they overflow? First find how many hours of runoff the sewers can handle: 240,000 / 1000 gallons/hour = <<240000/1000=240>>240 hours Then divide that time by the number of hours per day to find how many days of rain the sewers can handle: 240 hours / 24 hours/day = <<240/24=10>>10 days #### 10 In a 50-question test with two marks for each question, Meghan learned that she scored 20 marks less than her friend Jose, who scored 40 more marks than their friend Alisson. Calculate the total score for the three in the test combined if Jose got 5 questions wrong? If you answer every question correctly in the test, the total possible marks are 50*2= <<50*2=100>>100 marks. If Jose got five questions wrong, he lost 5*2 = <<5*2=10>>10 marks because each question has two marks. Therefore, Jose scored 100-10 = <<100-10=90>>90 marks on the test. Meghan scored 20 marks less than that which Jose got, a total of 90-20 = <<90-20=70>>70 marks. The total marks that Jose and Meghan scored in the test are 70+90 = <<70+90=160>>160 Alisson scored 90-40 = <<90-40=50>>50 marks in the examination, 40 marks less than that which Jose scored on the test. The total number of marks that the three scored in the test is 160+50 = <<160+50=210>>210 #### 210 Christopher uses 1 packet of a sugar substitute in his coffee. He has 2 coffees a day. The packets come 30 to a box and cost $4.00 a box. How much will it cost him to have enough sugar substitutes to last him 90 days? He uses 1 packet per cup of coffee and he has 2 cups a day so that's 1*2 = <<1*2=2>>2 packets He wants enough to last him 90 days and he uses 2 packets a day so that's 90*2 = <<90*2=180>>180 packets The packets come 30 to a box and he needs 180 packets so that's 180/30 = <<180/30=6>>6 boxes of sugar substitute Each box costs $4.00 and he needs 6 boxes so that's 4*6 = $<<4*6=24.00>>24.00 #### 24 Emma got $2000 from the bank. She bought $400 of furniture and gave 3/4 of the rest to her friend Anna. How much is left with Emma? Emma had $2000 - $400 = $<<2000-400=1600>>1600 left after buying furniture Emma gave Anna 3/4 * $1600 = $<<3/4*1600=1200>>1200 So, Emma is left with $1600 - $1200 = $<<1600-1200=400>>400 #### 400 John gets lost on his way home. His normal trip is 150 miles and would take him 3 hours. He ends up driving 50 miles out of the way and has to get back on track. How long did the trip take if he kept the same speed? His speed is 150/3=<<150/3=50>>50 mph He was detoured 50*2=<<50*2=100>>100 miles So that adds 100/50=<<100/50=2>>2 hours So the total trip was 3+2=<<3+2=5>>5 hours #### 5 Madeline needs $1200 to pay rent, $400 for groceries, $200 for medical expenses, and $60 for utilities. She also wants to save $200 in case of an emergency. She makes $15 per hour at her job. How many hours will Madeline need to work this month? Madeline needs 1200+400+200+60+200 = $<<1200+400+200+60+200=2060>>2060 to pay all of her bills. She will need to work $2060/$15 per hour = 137.33 hours. She will need to work 138 hours to pay all of her bills #### 138 Arthur knows that he needs to finish 800 pages of reading over the summer. He has read 80% of a 500-page book and 1/5 of a 1000 page book. How many more pages does he need to reach to meet his goal? He read 400 pages from the 500 page book because 500 x .8 = <<500*.8=400>>400 He read 200 pages from the 1000 page book because 1000 x (1/5) = <<1000*(1/5)=200>>200 He has read 600 pages in total. He needs to read 200 more pages to reach 800 pages because 800 - 600 = <<800-600=200>>200 #### 200 In a Volleyball competition, Lizzie was able to score 4 points. Nathalie's score is 3 more than Lizzie's score and Aimee's score is twice the score of Lizzie and Nathalie combined. The rest of the points were made by their teammates. If the whole team was able to score 50 points, how many points did their teammates make? Nathalie's score is 4 + 3 = <<4+3=7>>7. And the total points of Nathalie and Lizzie when combined is 7+4= <<7+4=11>>11. So, the total score of Aimee is 11 x 2 = <<11*2=22>>22. Lizzie, Nathalie, and Aimee's total score is 22 + 11 = <<22+11=33>>33. Therefore, their teammates were able to score 50 - 33 = <<50-33=17>>17. #### 17 Jason drives past 3 convenience stores on his way to work. The distance between the first store and the second store is 6 miles. The distance between the second store and third store is 2/3rds longer than the distance between the first two stores. The distance from his house to the first store and the last store to work is the same, 4 miles. How long in miles is Jason's commute to work? First find the additional distance between the second store and the third store: 6 miles * 2/3 = <<6*2/3=4>>4 miles Then add that to the distance between the first two stores to find the total distance between the second and third stores: 4 miles + 6 miles = <<4+6=10>>10 miles Then add the distance between the first two stores, the distance from Jason's house to the first store, and the distance from the last store to work: 10 miles + 6 miles + 4 miles + 4 miles = <<10+6+4+4=24>>24 miles #### 24
