Andrea's growing post

*cheers* It logged in! It logged in! YAY! Yes, I know this is the second growing post.

1. (a) Create a T-Chart showing how many baseball cards Jack has at the end of the next 4 months.

(b) Create an algebriac formula based upon the problem above.
180+25(n)=280 n=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?

When Jack turns 12, he'll have a total of 1380 baseball cards.

2. 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 there will be four people at the party (counting herself) how many pizzas should she order? Jackie will have to order 2 pizzas for the party.

(b) If two more people show up at the party, how many more pizza's does she need to order?
Jackie will have to order just one more pizza.

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

(a) Calculate how much money Kathy will have in one year.
Kathy will have $200.00 at the end of the year.

(b) Suppose Kathy counted wrong and she really has $25 in her account instead of $20. Change the algebraic formula to reflect this miscalculation. 25+15(12)=205 Kathy would have saved $205 instead of $200 at the end of the year.

4.Solve the following equations. Show all of the steps that are needed.
(a) 3n+4n+7=2n+12
