Consumer Math help please???
I've asked both my consumer math and even algebra teachers for help, and they've tried explaining it to me, but my brain just doesn't get it. If you could help me I would greatly appreciate it! No rude people please... :))

1.You want to purchase a hosue in 7 years. The etimated cost is180,000.00 and you want to make a 20% down payment. How much do you need to save per month in order to cover your down payment?

2. You are planning to attend a 2-year college at a cost of $8,278.00/yr for your associate's degree and then 2 years more at a university costing $14,675.00/yr for your bacherlor's degree. Your parents want you to pay 10% of the cost. How much of your higher education cost is your responsibility?

3. You have a part-time job paying $8.95/hr and your deductions are FICA (7.65%), federal tax withholding (9.3%), and state tax withholding (5.8%). You save $30.00/wk for a savings account. If you work 15 hours/wk, how much discretionary income is left each week?

4. You invest $3,756.00 and buy 100 shares of a company's stock. Their value increases by 12%. How much is each share worth?

5. You invest $5,175.00 in a stock plan. It increases 9% the first year, and then loses 5% of its value the second year. What is your gain compared to your original investment?

6. Your parents are planning to rent you an apartment when you go to college. The annual contract is $535.00/month with a 2 month penalty for breaking the lease. The month-to-month contract is $615.00/month. What is the difference in the amount paid if you leave after 8 months?

1.

you want 20% of 180000 so you want $36000

divide that amount by 84 months(7 years) and you'll have how much you need to save each month. 

2. 2 years at 8278      = 8278 x 2
    2 years at 14675    = 14675 x 2

calculate th cost of the education and then find 10% of the amount... which is simply a case of moving the decimal point 1 place left. 

hope it helps
