managing my money
Hi Class!We have been learning and working with percents in equations and proportions. Here is your assignment for today:You have just graduated college and have found your dream job as a ________ (insert job here - i.e. teacher, writer, actor, pro football player, doctor, nurse, etc.)! Let's pretend you will be making around $1200 per month, depending on overtime, bonuses, etc. Now here is the deal - you need to make sure you manage your money wisely. Answer the following questions:
1) Your rent plus utilities (gas, water, internet, phone, etc.) is $540 a month! What percentage of your monthly income is this?2) You spend about 6% of your income per month on your cell phone bill! What amount is this?3) You usually spend around $200 per month on groceries. Find this percentage.4) You spend about $40 per week on gas filling your car's gas tank! What percentage of your monthly income is spent on gas?
5) You like to use the remaining money and split it - using 60% on entertainment (movies, shopping, etc.) and putting the other 40% in savings. About how much money is spent on entertainment and how much is put in savings?
This should be a post on your blog. When you finish, move onto Study Island. :)
My dream job would be a specialist in human mind and body interactions (psychology)
“The science that deals with mental processes and behavior.
The emotional and behavioral characteristics of an individual, group, or activity.
Subtle tactical action or argument used to manipulate or influence another:
The branch of metaphysics that studies the soul, the mind, and the relationship of life and mind to the functions of the body.”
My utilities are 45% of my average income.
My cell phone bill is $72 a month that is 6% of my income.
On my $200 groceries I use 17% of my money.
I use 13% of my money on gas each week.
I have $288 left in my pocket. On entertainment I spend $172.80 each month. I save $115.20 each month.

polymonials
From the video and the websites I learned or became more clearer on some things. One thing I became more clear on is what Mono, Bi , and Tri mean. mono means one; bi means two; and tri means three. One thing that I learned was ia trick abouut how to think when combining like terms. When you have x to the third and x to the 2nd theycannot be combined because x^3 is like an apple and x^2 is like an orange. When grouping like things together you cannot put apples and oranges together.

One heading I chose was 30 Days 30 Ways To Save: The Bedfan. We spend a lot of money each year on air conditioning. My dad always cranks up the air at night. Instead he could put the bedfan on the bottom of his bed. Then since he likes to be cold and my mom doesn’t they could set it at my dads feet or in between them if they choose. I learned that there is a cheap way to keep cool during the night. The only thing that would make it better is if it was cheaper to buy.
The other heading I chose was 30 Days 30 Ways to Save: Slash your grocery bill. I chose this because our grocery bill is about 150 dollars a week or more. by getting organic foods and the off-brand chips and granola bars we can save a ton of money. Even my dad will save money grocery shopping (he likes buying the most expensive food because he thinks it tastes better = ] ) by simply looking for the cheaper option.

b. 2.09 x 13.7=$23.66
