question:Sam is stocking up on canned tuna. He got 9 cans at the supermarket, and had 5 coupons for 25 cents off a single can per coupon. He paid 20 and got 5.50 in change. How many cents does a can of tuna cost?
answer:His total without the coupons was 20 - 5.50 = <<20-5.5=14.50>>14.50 He had 5 coupons that each saved him 25 cents, so the full price of all the tuna is 14.50 + 5*0.25 =15.75. He bought 9 cans of tuna, so each can costs 15.75 / 9 = <<15.75/9=1.75>>1.75 As 1 dollar has 100 cents 1.75 * 100 = <<1.75*100=175>>175 cents 175
question:Kimberly loves gumballs and will trade almost anything she owns for them. A friend knows that Kim has a bunch of shiny new earrings that she loves. She agrees to give Kim 9 gumballs for each pair of earrings. On the first day, Kim brings her 3 pairs of earrings. On the second she brings her twice as many. On the third day, she brings 1 less than she brought on the second day. If Kim eats 3 gumballs a day, how many days will the gumballs last?
answer:On day 2 Kim trades 6 earrings because 3 x 2 = <<6=6>>6 On day 3 Kim trades 5 earrings because 6 - 1 = <<6-1=5>>5 In total she trades 14 pairs of earrings because 3 + 6 + 5 = <<3+6+5=14>>14 She trades these for 126 gum-balls because 14 x 9 = <<14*9=126>>126 These last her 42 days because 126 / 3 = <<126/3=42>>42 42
question:Billy wants to watch something fun on YouTube but doesn't know what to watch. He has the website generate 15 suggestions but, after watching each in one, he doesn't like any of them. Billy's very picky so he does this a total of 5 times before he finally finds a video he thinks is worth watching. He then picks the 5th show suggested on the final suggestion list. What number of videos does Billy watch?
answer:Billy has 15 suggestions generate for him 5 times for 15*5=<<15*5=75>>75 videos. There are 15-5 = <<15-5=10>>10 shows in the final set of suggestions he doesn't consider This means he picks the 75 - 10 = <<75-10=65>>65th show YouTube suggests 65
question:Exactly twofifths of NBA players who signed up for a test are aged between 25 and 35 years. If threeeighths of them are older than 35, and a total of 1000 players signed up, how many players are younger than 25 years?
answer:Two-fifths of 1000 players is (2/5)*1000 = <<(2/5)*1000=400>>400 players Three eights of 1000 players is (3/8)*1000 = <<(3/8)*1000=375>>375 players The total number of players 25 or older is 400+375 = <<400+375=775>>775 The number of players younger than 25 years is 1000-775 = <<1000-775=225>>225 players 225
