### Kim's Growing Post

Question #1: solve all 3 parts of the problem below

Jack collects baseball cards. Jack has 180 baseball cards in his collection. At the end of each month Jack bys 25 baseball cards to add to his collection.

a) Create a T-chart showing how many basball cards Jack has at the end of the next 4 months.

b) Create an algebraic formula based upon the probelm above

180 + 25 (n) = the number of cards

n = the month

c) If Jack just turned 8 years old this month and Jack continues to buy the same amount of baseball cards each month, how many baseball cards will Jack have when he turns 12?

If you use the algebraic formula, all you have to do is: 180 + 25 (n) = the number of cards. In this case, the answer would be 1380 because you take 12 - 8 = 4. Then you take 4 (which are the years he has until he turns 12) and you times it by 12 (which is the total months in a year) and you will get 48, then if you use 48 as the variation (n), and you do the algebraic formula, you will get 1380 as your answer.

Question #2: Use the chart to figure out the questions below.

Jackie is planning on having a pizza party with some of her friends. She is trying to figure out how many pizza's to order. She knows that each pizza has six slices of pizza.

a) If Jackie thinks that htere will be four people at the party (counting herself) how many pizza's should she order?

Jackie should order 2 pizza's because there are a total of 4 people (counting Jackie) and each person eats 3 slices and each pizza contains 6 slices and if you look at the chart above, you will see that 4 people need 12 slices and 12 slices means 2 pizzas in total. (this is the correction that I have made, the colour yellow)

b) If two more people show up at the party how many more pizza's does she need to order?

Jackie needs to order 3 pizza's in total because every 2 people eat up a total of 1 pizza so if there are 6 people, 6 divided by 2 is 3, Jackie will need to order 3 pizza's for her party.

Question #3: Answer the questions below based upon this information.

Kathy has $20 in her savings account. Each month she adds another $15 to her savings acount. In order to caculate how much money she will have in one year Kathy has created this algebraic formula: 20 + 15n = Savings amount.

a) Caculate how much money Kathy will have in one year.

I got the answer of $200 which is the money that Kathy will have in one year. I got that answer by using Kathy's formula which is 20 + 15n (n = 12). I multiplied 15 by 12 (which are the months in a year) and I got 180. After that, I added 20 to 180 and got $200.

b) Suppose Kathy counted wrong and she really has $25 in her account instead of $20. Change the algebraic formula to reflect this miscaculation.

If Kathy did counted wrong and she had $25 in her account then all you have to do is change the number 20 to 25 and for example, it will be like this: 25 + 15n = savings amount. So Kathy will have a total of $205 if she made the miscaculation.

Question #4: solve the following equations. Show all of the steps that are needed. ( we did not need to do these questions, so I do not have them)

GRAETA JOB!!!!!!!!!!!!!!! SMIILIIES

The only small problem is that you stated each person eats 2 pieces of pizza, but the graph does not tell us that.

Otherwise it is a great post!

Remember that you didn't have to do question 4, and there are some mistakes so I won't correct it right now.

hey Kim! great job it must of took u a long time to write all that down. It's Amalia.
