A) Create a T-chart showing how many baseball cards Jack has at the end of the next four months.



b) Create an algebraic formula based upon the problem above. 180 + 25(n)= # of cards

180+25(4)= 280180 + 25(n)= # of cards


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 will have collected a total of 1380 baseball cards. [ 180+25(48)= 1380]

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 pizza's should she order?

She would have to order 2 pizzas .

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

If more people show up she will have to order 1 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 saved up $200 in one year. [20+15(12)=200]

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

Kathy would have saved up $205 in a year. [25+15(12)=205]
