A family has three adults and children, both girls and boys. They went out for a family trip and prepared 3 dozen boiled eggs for the trip. Every adult got 3 eggs, and the boys each received 1 more egg than each girl since the girls had some snacks. How many boys went on the trip if the number of girls was 7 and each girl received an egg?

The total number of eggs the family had is 3 * 12 =

<<3*12=36>>36 eggs If each adult received 3 eggs, the total number of eggs they got is 3 * 3 = <<3*3=9>>9 eggs. The children shared 36 - 9 = <<36-9=27>>27 eggs Since each girl received an egg, the boys shared 27 - 7 = <<27-7=20>>20 eggs If each boy received 1 egg more than each girl, each received 1+1 = <<1+1=2>>2 eggs The boys received 20 eggs, and if each got 2 eggs, then 20/2 = <<20/2=10>>10 boys went on the trip #### 10 Mary used 15 gallons of fuel this week. Last week she used 20% less. How much fuel did she use in total for the two weeks? Last week, she used 15 gallons * 0.2 = <<15*0.2=3>>3 gallons less fuel than she used this week. This means that she used 15 gallons – 3 gallons = <<15-3=12>>12 gallons of fuel last week. In total, Mary used 15 gallons + 12 gallons = <<15+12=27>>27 gallons of fuel. #### 27 May can knit 3 scarves using one yarn. She bought 2 red yarns, 6 blue yarns, and 4 yellow yarns. How many scarves will she be able to make in total? May will be able to make 2 x 3 = <<2*3=6>>6 red scarves. She will be able to make 3 x 6 = <<3*6=18>>18 blue scarves. And she will be able to make 4 x 3 = <<4*3=12>>12 yellow scarves. Therefore the total scarves she can make is 12 + 18 + 6 = <<12+18+6=36>>36. #### 36 For every 1 minute that Carlotta sings on stage during the final opera performance, she spends an additional 3 minutes practicing and 5 minutes throwing temper tantrums. If her final stage performance is 6 minutes long, what is the total combined amount of time, in minutes, that she spends practicing, throwing tantrums, and singing in the final stage performance? For each 6 minutes she performs, Carlotta spends 6 * 3 minutes = <<6*3=18>>18 minutes practicing. For each 6 minutes she performs, Carlotta throws tantrums for 6 * 5 minutes = <<6*5=30>>30 minutes. Thus, in total, for each 6 minutes of performance time, she spends 18 minutes + 30 minutes + 6 minutes = 54 minutes on all three activities. #### 54 Phillip's mother asked him to go to the supermarket to buy some things and gave him $95, so he spent $14 on oranges, $25 on apples and $6 on candy. How much money does he have left? If we add everything Phillip bought, we will have: $14 + $25 + $6 = $<<14+25+6=45>>45 He spent $45, and we know that he had $95 dollars, so now we have to subtract: $95 - $45 = $<<95-45=50>>50 #### 50 Pam has some bags of apples. Each of her bags has as many apples as 3 of Gerald's bags. Gerald's bags have 40 apples each. If Pam has 1200 apples in total, how many bags of apples does she have? Each of Pam's bags contain 40*3=<<40*3=120>>120 apples. Pam has 1200/120=<<1200/120=10>>10 bags of apples. #### 10 Chelsea has 24 kilos of sugar. She divides them into 4 bags equally. Then one of the bags gets torn and half of the sugar falls to the ground. How many kilos of sugar remain? Each bag has 24/4=<<24/4=6>>6 kilos of sugar. 6/2=<<6/2=3>>3 kilos of sugar falls to the ground. 24-3=<<24-3=21>>21 kilos of sugar remains. #### 21 Bert fills out the daily crossword puzzle in the newspaper every day. He uses up a pencil to fill out the puzzles every two weeks. On average, it takes him 1050 words to use up a pencil. How many words are in each crossword puzzle on average? At 7 days a week, it takes Bert 2 * 7 = <<2*7=14>>14 days of daily crossword puzzles to use up a pencil. Since Bert does one puzzle a day, each crossword puzzle has 1050 / 14 = <<1050/14=75>>75 words. #### 75 There were sweets on the table. Jack came and took half of all the candies and 4 more candies. Then Paul came and took the remaining 7 sweets. How many sweets were on the table at first? Jack took 4 more candies than the half, and Paul took the rest, which means 7 + 4 = 11 candies were half of all candies. That means at first there were 11 * 2 = <<11*2=22>>22 candies. #### 22 Basil gets 1/2 of a dog cookie in the morning and before bed. She gets 2 whole cookies during the day. Basil’s cookies are packaged with 45 cookies per box. How many boxes will she need to last her for 30 days? Basil gets 1/2 in the morning and 1/2 at bedtime so she gets 1/2+1/2 = <<1/2+1/2=1>>1 whole cookie Basil also gets 2 whole cookies during the day so all total she gets 2+1 =<<2+1=3>>3 whole cookies She needs cookies for 30 days and eats 3 a day so she needs 30*3 = <<30*3=90>>90 cookies Her cookies come 45 per box and she needs 90 cookies so she needs 90/45 = <<90/45=2>>2 boxes of cookies #### 2
