tonythetigers' growing "PIZOST"

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 buys 25 baseball cards to add to his collection.

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



b) create an algebraic formula based upon the problem above.

180+25b

180+25(4)

180+100 = 280 baseball 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?

180+25c

180+25(48)

180+1200 = 1380 baseball cards

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 there will be four people at the party(counting herself) how many pizza's should she order?

She should order two pizza's because each of the four people including herself will get three slices each and the pizza holds 6 slices in each pizza box.

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

She needs to order one more pizza because the two new people who came will get 3 slices each, finishing the pizza.

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 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.

20+15n =

20+15(12) =

20+180 = $200 in saving account in one year

12= 1 year ( n = 12 )
Kathy will have $200 in her savings account in one 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+15n =

25+15(12) =

25+ 180 = $205 in saving account in one year
Kathy will have $205 in her savings account in one year if she did miscalculated.
