Robe's car broke and he used $10 from his savings to pay for the repair. Before the repair, he bought 2 kinds of spare parts. A corner light that costs twice the price of the repair fee, and two brake disks; each disk cost thrice the price of the corner light. After that, he had $480 savings left. How much money did Robe have saved before his car broke?

The corner light cost $10 x 2 = $

<<10*2=20>>20. Each brake disk costs $20 x 3 = $<<20*3=60>>60. So, the total price of the brake disks is $60x 2 = $<<60*2=120>>120. He spent $10 + $20 + $120 = $<<10+20+120=150>>150 for the repair. Therefore, Robe has saved $480 + 150 = $<<480+150=630>>630 before his car broke. #### 630 Ralph has $54.00 worth of products in his cart. At the register, he asks if he could have a 20% discount on an item with a small issue. This item is $20.00 to start. They agree. Ralph also has a 10% coupon on his purchase, which he uses after the 20% discount on the item with the small issue. How much will all of his items cost? They approved 20% off of the $20.00 item so .20*20 = $<<20*.01*20=4.00>>4.00 The item has a $4.00 discount which can be applied from his final total of $54.00 so 54-4 = $<<54-4=50.00>>50.00 Now he can use his 10% coupon on the $50.00 total so .10*50 = $<<10*.01*50=5.00>>5.00 The total was $50.00 but his $5.00 discount now makes it 50-5 = $<<50-5=45.00>>45.00 #### 45 Arnold owns three cars. The first car averages 50 miles per gallon of gas. The second car averages 10 miles per gallon of gas. And the third car averages 15 miles per gallon of gas. He splits his 450-mile monthly driving mileage equally amongst his three cars. If gas costs $2 per gallon, how much does he spend on gas each month? He drives each vehicle 150 miles because 450 / 3 = <<450/3=150>>150 The first car will need 3 gallons of gas because 150 / 50 = <<150/50=3>>3 The second car will need 15 gallons of gas because 150 / 10 = <<150/10=15>>15 The third car will need 10 gallons of gas because 150 / 15 = <<150/15=10>>10 He will need 28 gallons in total because 3 + 15 + 10 = <<3+15+10=28>>28 This will cost him $56 because 28 x $2 = $<<28*2=56>>56 #### 56 Mary is making a spinach quiche. She takes 40 ounces of raw spinach and cooks it until it's 20% of its initial volume. If she mixes the spinach with 6 ounces of cream cheese and 4 ounces of eggs, what is the total volume of the quiche? First find the cooked volume of the spinach: 40 ounces * 20% = <<40*20*.01=8>>8 ounces Then add that to the volume of the other ingredients to find the total volume: 8 ounces + 6 ounces + 4 ounces = <<8+6+4=18>>18 ounces #### 18 Before he lost one, Policeman O'Brien had 5 more than twice as many hats as fire chief Simpson. If fire chief Simpson has 15 hats, how many hats does Policeman O'Brien now have? Twice as many hats as fire chief Simpson has is 2 * 15 = <<2*15=30>>30 hats. 5 more than 30 hats is 30 + 5 = <<30+5=35>>35 hats. One less than 35 hats is 35 - 1 = <<35-1=34>>34 hats. #### 34 Out of the 200 apples in an orchard, 40 percent were rotten. Also, 70 percent of the rotten apples smelled. How many rotten apples in the orchard did not smell? The number of apples in the orchard which were rotten is 40/100*200 = <<40/100*200=80>>80 Out of the 80 rotten apples, 70/100*80 = <<70/100*80=56>>56 were smelling. The number of rotten apples in the orchard which were not smelling is 80-56 = <<80-56=24>>24 #### 24 In a graduation ceremony, each graduate can bring their 2 parents. Twenty teachers and half as many administrators will also attend the graduation ceremony. If there are 50 graduates, how many chairs must be prepared for the ceremony? There will be 50 x 2 = <<50*2=100>>100 parents that are expected to attend. 20/2 = <<20/2=10>>10 administrators will attend. Hence, 50 graduates + 100 parents + 20 teachers + 10 administrators = 180 chairs must be prepared. #### 180 Sophie's aunt gave her $260 to spend on clothes at the mall. She bought 2 shirts that cost $18.50 each and a pair of trousers that cost $63. She then decides to purchase 4 more articles of clothing with her remaining budget. How much money would each item cost if she split the cost of each item evenly? Sophie spent $18.50 × 2 = $<<18.5*2=37>>37 on the two shirts. She spent in total $37 + $63 = $<<37+63=100>>100 on clothes so far. She has $260 - $100 = $<<260-100=160>>160 left to spend on clothes. Sophie has $160 ÷ 4 = $<<160/4=40>>40 left to spend on each additional item of clothing #### 40 Jessie's community built a new hedge. Each section of the hedge used 30 pieces of concrete blocks that cost $2 per piece. The hedge has eight sections. How much did they spend on the concrete blocks? They used 30 x 8 = <<30*8=240>>240 concrete blocks for the eight sections. So, they spent 240 x $2 = $<<240*2=480>>480 on the concrete blocks. #### 480 Jaden had 14 toy cars. Then he bought 28 cars from the toy store and got 12 cars for his birthday. Jaden gave 8 of the toy cars to his sister and 3 to his friend Vinnie. How many toy cars does Jaden have left? Jaden had a total of 14 cars + 28 cars = <<14+28=42>>42 cars after buying from the toy store. His total then increased to 42 cars + 12 cars = <<42+12=54>>54 cars on his birthday. Jaden then had 54 cars - 8 cars = <<54-8=46>>46 cars after giving 8 to his sister. Finally after giving his friend, Vinnie, a few cars Jaden had 46 cars - 3 cars = <<46-3=43>>43 cars left. #### 43
