Transcript of 6th grade Math Problem

A Yummy Problem By: Amanda Eng and
Sania Hussain The Problem Well, we know that both Juliet and Bob cut their cake into 4 slices. We also know that Bob has a five percent discount for kids 10 and under, while Juliet has a 2 percent discount for kids 10 and under. We also know that Bob is selling each slice of cake for $5, while Juliet is selling one slice for $4. We also know that on Monday Bob sold 2 slices of cake to an 8-year old and another one to an adult. What We Know Solution #1 Well, first we have to find out what is 5% of $5. To do that, you would have to multiply 5 x .05. If you multiplied correctly, you should get .25. So, to find how much Bob earned overall, you would have to do $5-$0.25+$5(the child's slice and the adult's slice). If you did this right, Bob earned a total of $9.75. To find how much Juliet earned, you would use the same method. You would change 2% into a decimal. You would multiply the decimal, by the $4. So, you would do .02 x $4. You should get .08. You subtract 0.08 from $4. You should get $3.92. You multiply that by 2, because there are 2 kids. You should get $7.84. Next you add $4 to $7.84 because of the adult. You should get $11.84. So, Juliet made more money. Solution #2 Well, you can make 5% into a fraction. When you do that, you'll know that 5% in a fraction is 5/100. Once you have your fraction you multiply. So, you solve this: 5/100 x $5. You'll find out what 5% percent of 5 is, which is $0.25. So you do $5-.25. Next you add $5 to your answer because Bob sold a slice to an adult, which is only $5. So, your final answer is $9.75.
Next you have to find out how much money Juliet made. We know Juliet sold 3 slices. She sold two of them to kids. So, they get 2% off. So, you change 2% to a fraction, and get 2/100. After that you multiply $4 by 2/100. You should get 8/100. You subtract 8/100 from $4. You should get $3.92, once you change the fraction into a decimal. You multiply that by 2, and get $7.84. Finally, you add $4 and get $11.84. So, Juliet made more money. Thanks for watching!
Bob bakes a cake. He cuts it into four slices. He sells each slice for $5. He gives a 5% discount on each slice for kids, 10 and under. Across the street, his friend Juliet is selling cake slices for $4 each. She cuts each cake into 4 slices, but gives a 2% discount on each slice for kids 10 and under as well. On Monday, Bob sold 2 slices. He sold 1 slice to a kid who’s 8 years old, and another one to an adult, who’s 30. Juliet sold 3 slices. She sold two slices to kids, one was 5 and one was 8, she sold the other one to an adult. Who made more money? We know that Bob baked a cake and cut it into 4 slices. He sells each slice for $5, and he gives a 5% discount for kids ages 10 and under. We know one day he sold 2 slices, one was to a kid and another one to an adult. We need to know how much money Bob made so we can find can compare the amount of money made to the amount of money Juliet made.
We know Juliet also sells cake. Each slice for $4 and she gives a 2% discount for kids 10 and under. We know one day she sold 3 slices. She sold 2 of them to kids and one to an adult. We need to know how much money she made. Let's find out. A New Problem Now that you know how to solve that problem let's see if you can solve this:
Bill bakes cakes. He cuts the slice into 4 slices. He sells each slice for $6. He gives a 3% discount on Tuesday for kids 10 and under. On Monday he sold 6 slices. On Tuesday he sold 4 slices. He sold 2 of them to kids, and the other 2 to an adult. Which day did he make more money? By how much? Answer Bob made more money on Monday.He made $0.36 cents more.
