Barbie enjoys buying jewelry. One day, she bought 12 pairs of earrings, and gave half of them to Alissa, making Alissa's total number of collections to be triple the number of earrings she was given. How many earrings does Alissa have now?

If 1 pair of earrings equals 2 earrings, then Barbie bought 12*2=

<<12*2=24>>24 earrings. Half of 24 earrings is 24/2=<<24/2=12>>12 earrings If receiving 12 earrings tripled Alissa's collection, then she now has 12*3=<<12*3=36>>36 earrings. #### 36 John Smith buys 3 cakes for $12 each and splits the cost with his brother. How much did he pay? The cakes cost 3*12=$<<3*12=36>>36 So he paid 36/2=$<<36/2=18>>18 #### 18 Ruth prepared sandwiches. She ate 1 sandwich and gave 2 sandwiches to her brother. Her first cousin arrived and ate 2 sandwiches. Then her two other cousins arrived and ate 1 sandwich each. There were 3 sandwiches left. How many sandwiches did Ruth prepare? Ruth's two cousins ate a total of 2 x 1 = <<2*1=2>>2 sandwiches. So there were 3 + 2 = <<3+2=5>>5 sandwiches left before her two cousins arrived. Before her first cousin arrived, there were 5 + 2 = <<5+2=7>>7 sandwiches. Ruth and her brother had 1 + 2 = <<1+2=3>>3 sandwiches altogether. Therefore, Ruth prepared 7 + 3 = <<7+3=10>>10 sandwiches." #### 10 Nina made a two-layer cake and a dozen cupcakes for her friend’s birthday party. Each layer of cake takes the same amount of sugar to make as a dozen cupcakes. Nina used 720 grams of sugar to bake everything. How many grams of sugar are in one cupcake? Nina made 2 cake layers which were equal to 2 x 12 = <<2*12=24>>24 cupcakes. She made the equivalent of 24 + 12 = <<24+12=36>>36 cupcakes in all. Thus, there are 720 / 36 = <<720/36=20>>20 grams of sugar in a cupcake. #### 20 Harry owns 3 geckos, 2 iguanas, and 4 snakes. If he spends $10 to feed each snake, $5 to feed each iguana, and $15 to feed each gecko every month, how much does he spend every year to feed all his pets? He spends $10/snake * 4 snakes = $<<10*4=40>>40 to feed his snakes every month He spends $5/iguana * 2 iguanas = $<<5*2=10>>10 to feed his iguanas every month He spends $15/gecko * 3 geckos = $<<15*3=45>>45 to feed his geckos every month So overall he spends $40 + $10 + $45 = $<<40+10+45=95>>95 to feed all his pets every month Therefore every year pet food costs him $95/month * 12 months = $<<95*12=1140>>1140 #### 1140 John has a raw squat of 600 pounds without sleeves or wraps. Sleeves add 30 pounds to his lift. Wraps add 25% to his squat. How much more pounds does he get out of wraps versus sleeves. Wraps add 600*.25=<<600*.25=150>>150 pounds to his lift So they add 150-30=<<150-30=120>>120 pounds more than sleeves #### 120 George and Amelia are picking oranges and apples at an orchard. George picks 45 oranges and 5 more apples than Amelia. Amelia picks 18 fewer oranges than George and 15 apples. How many fruits do they pick altogether? Amelia picks 45 - 18 = <<45-18=27>>27 oranges. The total number of oranges that they pick is 45 + 27 = <<45+27=72>>72. George picks 15 + 5 = <<15+5=20>>20 apples. The total number of apples that they pick is 20 + 15 = <<20+15=35>>35. So, they pick 72 + 35 = <<72+35=107>>107 fruits altogether. #### 107 There were 180 apples in each crate. 12 such crates of apples were delivered to a factory. 160 apples were rotten and had to be thrown away. The remaining apples were packed into boxes of 20 apples each. How many boxes of apples were there? The total number of apples delivered was: 180 apples x 12 crates = <<180*12=2160>>2160 apples So, the number of remaining apples after throwing away the rotten ones was: 2160 apples – 160 apples = <<2160-160=2000>>2000 apples And now, we can find the total number of boxes of apples by dividing the remaining number of apples by the number of apples per box: 2000 apples / 20 apples/box = <<2000/20=100>>100 boxes of apples. #### 100 Matt is playing basketball. In the first quarter, he made 2-point shots four times and 3-point shots twice. How many points did he score for that quarter? His total score for the 2-point shots is 2 x 4 = <<2*4=8>>8. His total score for the 3-point shots is 3 x 2 = <<3*2=6>>6. His total score for the first quarter is 8 + 6 = <<8+6=14>>14. #### 14 Maria has 4 dimes, 4 quarters, and 7 nickels in her piggy bank. Her mom gives her 5 quarters. How much money, in dollars, does Maria have now? Maria has 4 + 5 = <<4+5=9>>9 quarters. The number of dollars from the quarters is 9 * $0.25 = $<<9*0.25=2.25>>2.25 The number of dollars from the dimes is 4 * $0.10 = $<<4*0.10=0.40>>0.40 The number of dollars from the nickels is 7 * $0.05 = $<<7*0.05=0.35>>0.35 The total number of dollars is $2.25 + $0.40 + $0.35 = $<<2.25+0.40+0.35=3>>3 #### 3
