On Monday 2445 bottles were sold, on Tuesday 900 bottles were sold, and 50 bottles each day for the rest of the week were sold (from Wednesday until Sunday). On Saturday, the supplier delivers an order for 650 bottles. How many bottles of sanitizer gel does the Drugstore have at the end of the week?

The number of bottles sold on Monday and Tuesday is 2445 + 900 =

<<2445+900=3345>>3345 bottles Each day of the rest of the week, 50 bottles were sold, that is 5 * 50 = <<50*5=250>>250 bottles sold. Now the total of bottles sold in a week is 3345 + 250= <<3345+250=3595>>3595 bottles The drugstore has in stock 4500 – 3595= <<4500-3595=905>>905 bottles Finally the drugstore has 905 + 650 the supplier brought = <<905+650=1555>>1555 bottles at the end of the week. #### 1555 There are 285 sweets in the bowl. If 49 of the sweets are red and 59 of the sweets are green, how many of the sweets are neither red nor green? There are 49 + 59 = <<49+59=108>>108 red or green sweets in the bowl There are 285 - 108 = <<285-108=177>>177 sweets that are neither red nor green #### 177 In a stationery store, there are three kinds of pencils. A pencil with an eraser, which costs $0.8 each, a regular pencil for $0.5 each, and a short pencil for $0.4 each. This store was able to sell 200 pencils with an eraser, 40 regular pencils, and 35 short pencils. How much money did the store make from these sales? For pencils with erasers, the store received a total of 200 * 0.8 = $<<200*0.8=160>>160. For regular pencils, the store received 40 * 0.5 = $<<40*0.5=20>>20. And for short pencils only 35 * 0.4 = $<<35*0.4=14>>14. In total, the store made 160 + 20 + 14 = $<<160+20+14=194>>194 from selling these pencils. #### 194 Lillian is making chocolate cupcakes to sell at a fundraiser. She only has 3 cups of sugar at home. She goes to the store and buys 2 bags of sugar. Each bag of sugar contains 6 cups. The batter uses 1 cup of sugar per 12 cupcakes. She needs 2 cups of sugar to make enough frosting for a dozen cupcakes. How many dozen cupcakes can she bake and ice with the sugar she has? The bags of sugar which she bought contain 2 * 6 = <<2*6=12>>12 cups. In total, she has 12 cups + 3 cups = <<12+3=15>>15 cups of sugar to use. She needs 1 cup + 2 cups = <<1+2=3>>3 cups of sugar to make the batter and frosting for a dozen cupcakes. Lillian has enough sugar to bake and ice 15 / 3 = <<15/3=5>>5 dozen cupcakes. #### 5 John buys 2 packs of index cards for all his students. He has 6 classes and 30 students in each class. How many packs did he buy? John has 6*30=<<6*30=180>>180 students So he bought 180*2=<<180*2=360>>360 packs #### 360 The three angles of a triangle add up to 180 degrees. The largest angle is 5 times bigger than the smallest. The middle angle is 3 times bigger than the smallest. How many degrees is the smallest angle? Let x be the smallest angle. The combination of the three is x + 3x + 5x = 9x. Thus 9x = 180. So x = <<20=20>>20. #### 20 The pet store can buy a goldfish for $.25 and sell it for $.75. The owner plans to use the profits from goldfish sales to buy a new tank, which costs $100. After one week, he is 45% short of the price. How many goldfish did he sell that week? He is $45 short because 100 x .45 = <<100*.45=45>>45 He earned $55 off goldfish because 100 - 45 = <<100-45=55>>55 He makes $.5 profit per goldfish because .75 - .25 = <<.75-.25=.5>>.5 He sold 110 goldfish that week because 55 / .5 = <<55/.5=110>>110 #### 110 Mark and James need a total of 14 dice that are 12 sided to play their game. Mark has a bag of 10 dice and 60% of them are 12 sided. James has a bag of 8 dice and 75% of them are 12 sided. How many dice will the boys need to buy to play their game? Mark has 60% 12 sided dice, so 60/100 * 10 dice in his bag = <<60/100*10=6>>6 12 sided dice. James has 75% 12 sided dice, so 75/100 * 8 dice in his bag = <<75/100*8=6>>6 12 sided dice. They will need to purchase 14 dice - 6 dice - 6 dice = <<14-6-6=2>>2 dice. #### 2 Anna ate 4 apples on Tuesday. On Wednesday, she ate double the apples she ate on Tuesday. On Thursday, Anna ate half the apples she ate on Tuesday. How many apples has Anna eaten by the end of these three days? On Tuesday, Anna ate 4 apples. On Wednesday, she ate 4 x 2 = <<4*2=8>>8 apples. On Thursday, she ate 4 / 2 = <<4/2=2>>2 apples. In total, Anna ate 4 + 8 + 2 = <<4+8+2=14>>14 apples. #### 14 In 2 years, Maxwell will be twice his sister's age. If his sister is now 2, how old is Maxwell now? In two years, Maxwell's sister will be 2 years + 2 years = <<2+2=4>>4 years old. Therefore, Maxwell will be 4 years x 2 = <<4*2=8>>8 years old in two years. Maxwell is now 8 years - 2 years = <<8-2=6>>6 years old. #### 6
