Tracy feeds each of her two dogs 1.5 cups of food per meal. She feeds her dogs thrice a day. How many pounds of food do her two dogs consume if 1 pound is equal to 2.25 cups?

Each dog consumes 1.5 x 3 =

<<1.5*3=4.5>>4.5 cups of food a day. In pounds, this is equal to 4.5/2.25 = <<4.5/2.25=2>>2. So both consume 2 x 2 = <<2*2=4>>4 pounds of food. #### 4 Mark is baking bread. He has to let it rise for 120 minutes twice. He also needs to spend 10 minutes kneading it and 30 minutes baking it. How many minutes does it take Mark to finish making the bread? First find the total rise time: 120 minutes * 2 = <<120*2=240>>240 minutes Then add the rise time to the baking and kneading time: 240 minutes + 10 minutes + 30 minutes = <<240+10+30=280>>280 minutes #### 280 James has 3 fish tanks. 1 of the tanks has 20 fish in it and the other two have twice as many fish each as the first. How many total fish do they have? The second and third tank each have 20*2=<<20*2=40>>40 fish So in total there are 20+40*2=<<20+40*2=100>>100 fish #### 100 Sarah interviewed 450 students at her school and asked them which fruit they liked best - oranges, apples, pears or strawberries. 70 students said they liked oranges, 120 students said they liked pears, and 147 students said they liked apples. How many students picked strawberries as their favorite fruit from the list? First, you have to add the number of students that liked the three other fruits. Therefore, you have to add 70 + 120 + 147. This gives you a sum of 337. We know that 450 students were interviewed, so you have to subtract 337 from 450 to get the number of students who liked strawberries. 450 - 337 = <<450-337=113>>113 students liked strawberries best out of all of the fruits. #### 113 Kendra and Laurel have shops that sell different brands of shoe collections. In 2014, Kendra made $8000 less than Laurel made in sales. However, in 2015, Kendra made 20% more money than Laurel made in 2014. If Laurel earned $30000 in 2014, calculate Kendra's total earnings in the two years. In 2015, Kendra's sales were 20/100 * $30000 = $<<20/100*30000=6000>>6000 more than Laurel's. So, Kendra's total sales for 2015 was $30000 + $6000 = $<<30000+6000=36000>>36000 If Kendra made $8000 less in 2014 than Laurel, she made $30000 - $8000 =$22000 in that year The total amount of money Kendra made in the two years is $22000 + $36000 = $<<22000+36000=58000>>58000 #### 58000 Mandy is ten years older than Jackson. Adele is 3/4 as old as Jackson. What's the total of their ages 10 years from now If Jackson is 20 years old now? In ten years, Jackson will be 20+10 = 30 years old. If Jackson is 20 now, Mandy is 20+10 = <<20+10=30>>30 years old. Ten years from now, Mandy will be 30+10 = <<30+10=40>>40 years old. The combined age of Jackson and Mandy ten years from now is 30+40 = <<30+40=70>>70 years Adele is 3/4 times as old as Jackson, meaning she is 3/4*20 = <<3/4*20=15>>15 years old. Adele's age will be 10+15 = <<10+15=25>>25 years old ten years from now. Altogether, Mandy, Jackson, and Adele will have a total of 25+70 = <<25+70=95>>95 years #### 95 Gerald is a furniture maker. He has 672 pieces of wood and he wants to make some tables and chairs. It takes 12 pieces of wood to make a table and 8 pieces of wood to make a chair. How many chairs can he make if he makes 24 tables? Each table takes 12 pieces of wood to make so 24 tables will take 24*12 = <<12*24=288>>288 There were originally 672 pieces of wood so now there are 672-288 = <<672-288=384>>384 pieces left 8 pieces of wood make 1 chair so 384 pieces can make 384/8 = <<384/8=48>>48 chairs #### 48 Carol sells tickets for an exhibition. During three days she sold tickets worth $960. One ticket costs $4. How many tickets on average did she sell during one of these three days? Carol sold 960 / 4 = <<960/4=240>>240 tickets during three days. So in one day, she sold on average 240 / 3 = <<240/3=80>>80 tickets. #### 80 John can read a book 60% faster than his brother. If his brother takes 8 hours to read a book, how long would it take John to read 3 books? Reading 60% faster means John's brother takes 1+.6=1.6 times as long as John to read So John reads a book in 8/1.6=<<8/1.6=5>>5 hours So it would take John 5*3=<<5*3=15>>15 hours to read 3 books #### 15 Amanda's car takes five fewer minutes to complete the same trip to the beach than the bus. If the bus takes 40 minutes to drive 80 miles to the beach, how many minutes will it take the car to make a round trip? If the bus takes 40 minutes to complete 80 miles of a trip, Amanda's car, which takes five fewer minutes to complete a trip than the bus, will take 40-5=<<40-5=35>>35 minutes to complete the trip. A round trip will take the car twice the time for going one way, a total of 35+35=<<35+35=70>>70 #### 70
