Stacy, Steve and Sylar have 1100 berries total. Stacy has 4 times as many berries as Steve, and Steve has double the number of berries that Skylar has. How many berries does Stacy have?

Let x be the number of berries Skylar has.

Steve has 2x berries

Stacy has 4(2x)=8x berries

1100=x+2x+8x

1100=11x

x =

<<100=100>>100 berries Stacy has 8(100)=<<8*100=800>>800 berries #### 800 A bicycle store is running a promotion. Every time a customer buys a bicycle, they will receive 2 bike clamps free with it. If the store sells 19 bikes in the morning and 27 bikes in the afternoon, how many bike clamps has the store given to customers? In the morning, the store gives away 19 bikes * 2 bike clamps = <<19*2=38>>38 bike clamps. In the afternoon, they give away 27 bikes * 2 bike clamps = <<27*2=54>>54 bike clamps. So in total, the store has given away 38 + 54 = <<38+54=92>>92 bike clamps. #### 92 Jon’s textbooks weigh three times as much as Brandon’s textbooks. Jon has four textbooks that weigh two, eight, five and nine pounds respectively. How much do Brandon’s textbooks weigh? Jon’s textbooks weigh 2 + 8 + 5 + 9 = <<2+8+5+9=24>>24 pounds. Thus, Brandon’s textbooks weigh 24 / 3 = <<24/3=8>>8 pounds. #### 8 Carl is having a party on Saturday and is inviting 15 guests. He would like to make sure everyone, including himself, has at least 2 glasses of punch. Each glass holds 12 ounces of punch. How many ounces of punch does he need to buy for the party? Including Carl, there will be 15 + 1 = <<15+1=16>>16 people at the party. Carl would like each person to be able to have 2 cups x 12 ounces = <<2*12=24>>24 ounces of punch.

How many miles did Molly ride on her bike? Molly rode for 16 – 13 = <<16-13=3>>3 years. She rode for 3 years x 365 days = <<3*365=1095>>1,095 days.

Eric, who loves walking by the beach, makes a note of this and goes home. The next day, he realizes only half the number of Oysters were on the rocks, and only 2/3 the number of crabs as the previous day are on the beach. How many oysters and crabs did he count in total in the two days? The first day he saw 50 oysters + 72 crabs = <<50+72=122>>122 animals. On the second day, he saw 1/2 * 50 oysters = <<1/2*50=25>>25 oysters. The number of crabs by the beach on the second day was 2/3 * 72 crabs = <<2/3*72=48>>48 He saw 48 crabs + 25 oysters = <<48+25=73>>73 animals on the second day. The total for the two days is 73 animals + 122 animals = <<73+122=195>>195 animals #### 195 Ken buys gummy vitamins.
