Camille's Growing Post #4

Question 1.) Formulas. We've learned how to write algebraic equations in the form of mx+b=y. Convert these two sentences into algebraic equations using the above formula.

Sentence 1: Scott is 2 years older than Donald who turns 12 in June 21st 2006. Write this sentence in the format of mx+b=y, then convert it into an expression which allows us to figure out the age of Scott.


Sentence 2: Elizabeth has $200 in her savings acount. She makes $40 every two weeks babysitting for her next door neighbors. If Elizabeth saves all of her money solve for how moch money she will have in one year.


Quaestion 2.) You need to create two questions for your classmates that cover different concepts (ex: T-Charts, patterns, equations, graphs etc.) that you have learned in this unit on Algebra. You need to show how to solve the questions. Your mark will be based upon the level of question's difficulty, and the effort put into your answer.

Question: Carlotta spent $35 at the market. This was seven dollars less than three times what she spent at the bookstore. How much did she spend there?
Let x answer the question-----How much did she spend there?

3x − 7 = 35

Question: Judy starts working at MacDonald in 24 hours. Every one hour, she receives $10.75. How much money did she collect in 10 hours?


Question 3.) 3. Reflection. You need to look back at the chart that we filled out during the first day of the unit. You now need to pick one concept that you coloured yellow or red and reflect in words what new skill that you learned on this topic.

I choose Can I use my words to create an algebraic formula? because I learned this so fast.

This is my example: (actually I have 3 examples.)

1.) 8n-3n+n=12+6------> eight multiplied by a number subtracted by three multiplied by a number added by a number is equal to twelve added by six.

2.) 11-4-2+3n=8n------> eleven subtrcted by four subtracted by two added by three multiplied by a number is equal to 8 multiplied by a number.

3.) 10+4n=14+2n------> ten added by four multiplied by a number is equal to fourteen added by two multiplied by a number.

Question 4.) Preparing for the final exam. You need to think about the year that has past in mathematics and decide which topic is your weakest, and what you need to learn during class review in order to prepare yourself for the final exam. It is not enough to say fractions, instead pick your weakest area of fractions, say the subtraction of fractions, and give an example of what you don’t understand.

You had problems with the first question. Scott = Donald + 2

donald age = 11 so 11 + 2= 13

Elizabeth's money = 40n + 200 where n = number of 2 week periods that she babysat for the nextdoor neighbours.

Otherwise this was a great post. You mark is 20/25
