Fred has 38 red marbles, half as many green ones, and the rest are dark blue. If he has 63 marbles, how many of them are dark blue?

Fred has 38/2 =

<<38/2=19>>19 green marbles. Fred has 63-38-19 = <<63-38-19=6>>6 dark blue marbles. #### 6 Laura bought 2 pairs of pants for $54 each and 4 shirts for $33 each. She gave $250 to the cashier. So how much change did she take? 54*2=$<<54*2=108>>108 is the price of 2 pairs of pants. 4*33=$<<4*33=132>>132 is the price of 4 shirts. 108+132=$<<108+132=240>>240 is the total price. So the cashier gave 250-240=$<<250-240=10>>10 change to Laura. #### 10 Mark bought a shirt, pants, and shoes for $340. What is the price of the pants knowing that the price of a shirt is three-quarters of the price of the pants and that the price of a shoe is ten dollars more than the price of the pants? Let X be the price of the pants. The price of the shirt is 3/4*X. The price of the shoes is X+10. The total amount paid is X + 3/4*X + X+10 = $340. Combining like terms we get X*11/4 + 10 = $340. Subtracting 10 from both sides we get X*11/4 = $330. Dividing both sides by 11/4 we get X = $120. #### 120 Nancy bought a pie sliced it into 8 pieces. She gave 1/2 to Joe and Darcy, and she gave 1/4 to Carl. How many slices were left? The total number of slices she gave to Joe and Darcy is 1/2 x 8 = <<1/2*8=4>>4. The total slice she gave to Carl is 1/4 x 8 = <<1/4*8=2>>2. Therefore, the total slices left is 8 - 4 - 2 = <<8-4-2=2>>2. #### 2 Elizabeth wants to buy the steak knives from a bridal registry as a wedding gift. The couple registered for 2 steak knife sets and each set contains 4 steak knives. If Elizabeth buys both sets and they cost $80.00 per set, how much does each single steak knife cost? Each steak knife set has 4 steak knives and Elizabeth bought 2 sets so there are 4*2 = <<4*2=8>>8 steak knives in total Each steak knife set costs $80.00 and she bought 2 sets so she spent $80*2 = $<<80*2=160.00>>160.00 Both sets cost $160.00 and there are 8 knives in total so each knife costs 160/8 = $<<160/8=20.00>>20.00 each #### 20 During a recent three-day trip to Italy, Keziah and her mom went mushroom picking. They sold all the mushrooms they picked on the first day for a total of $58. The day after, they picked 12 mushrooms. On the last day, they picked double the mushrooms they had picked the previous day. If the price per mushroom was $2, what is the total number of mushrooms they picked? Since each mushroom cost $2, on the first day Keziah and her mom picked and sold 58/2 = <<58/2=29>>29 mushrooms After picking 12 mushrooms on the second day, the cumulative total became 29 + 12 = <<12+29=41>>41 mushrooms On the third day, they picked double the previous day, which translates to 2 * 12 = <<2*12=24>>24 mushrooms It therefore means that over the three days, Keziah and her mom picked a total of 41 + 24 = <<41+24=65>>65 mushrooms. #### 65 Jenny lives 5000 feet from her school, and every day she walks home. One day as she was walking home from school, she dropped 1 kernel of popcorn per 25 feet she walked. Later that evening, a squirrel came and ate one-quarter of the popcorn Jenny had dropped on her way home. If Jenny walks to school the following morning and counts the popcorn on the ground, what is the total number of popcorn kernels she will find remaining on the ground? She originally dropped 5000/25=<<5000/25=200>>200 kernels of popcorn. The squirrel ate 200/4=<<200/4=50>>50 kernels of popcorn. Therefore, 200-50=<<200-50=150>>150 kernels of popcorn remain on the ground. #### 150 All people named Barry are nice, while only half of the people named Kevin are nice. Three-fourths of people named Julie are nice, while 10% of people named Joe are nice. If a crowd contains 24 people named Barry, 20 people named Kevin, 80 people named Julie, and 50 people named Joe, how many nice people are in the crowd? If all people named Barry are nice, and the crowd contains 24 people named Barry, then 1*24=<<24*1=24>>24 of these people are nice. If only half of people named Kevin are nice, and the crowd contains 20 people named Kevin, then 0.5*20=<<0.5*20=10>>10 of these people are nice. If three-fourths of people named Julie are nice, and the crowd contains 80 people named Julie, then (3/4)*80=<<3/4*80=60>>60 of these people are nice. If 10% of people named Joe are nice, and the crowd contains 50 people named Joe, then 0.1*50=<<0.1*50=5>>5 of these people are nice. In total, the crowd contains 24+10+60+5=<<24+10+60+5=99>>99 people who are nice. #### 99 James buys 20 coins of a cryptocurrency at $15 each. The value of the coins increases by 2/3. He sells coins to recoup his original investment. How many coins did he sell? His original investment was 15*20=$<<15*20=300>>300 The value of his investment increases by 15*2/3=$<<15*2/3=10>>10 per coin So each coin was worth 15+10=$<<15+10=25>>25 So he sold 300/25=<<300/25=12>>12 coins #### 12 Randy has some money. He spent $10 buying his lunch. He spent a quarter of the money he had left on an ice cream cone. If the ice cream cone cost $5, what is the amount of money, in dollars, Randy had at first? Randy has 5*4=<<5*4=20>>20 dollars left after buying lunch. Randy had 20+10=<<20+10=30>>30 dollars at first. #### 30
