Answer: she needs to save $6510
Step-by-step explanation:
In the first year, she expects her total cost to be $9,850. Wei has already saved $1,220 for college. This means that the remaining amount that she needs would be
9850 - 1220 = $8630
she expects to receive grants and scholarships that total $2,120. Therefore, the amount of money that she should save to be able to pay for her first year of college would be 8630 - 2120 = $6510
Answer:
He will have $39,750 at the end of five years.
Step-by-step explanation:
This is a simple interest problem.
The simple interest formula is given by:
In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.
After t years, the total amount of money is:
In this question:
Interest earned:
Total amount:
He will have $39,750 at the end of five years.
Remark
Break this down into smaller steps. Do as much as you can before considering the next part.
Step One
multiply (6*10^5) * (5 * 10^-9)
5 * 6 = 30
10^5 * 10-9 = 10^(5 - 9) = 10^-4
30 * 10^-4. But scientific notation expresses numbers between 1 and 10
30 * 10^-4 = 3 * 10^1 * 10^-4 = 3 * 10^(1 -4) = 3 * 10^-3
That's about as far as you can go with this step.
Step Two
Divide 3*10^-3 by 3 * 10^-3
When you divide anything at all by itself, you get 1.
For example 130011 / 130011 = 1
So
3 * 10^-3 divided by 3*10^-3 = 1
Answer: 1
Answer:
(5/3 x - k)/c =b
Step-by-step explanation:
x = 3 / 5 (cb+k)
Multiply each side by 5/3
5/3x =5/3* 3 / 5 (cb+k)
5/3x = (cb+k)
Subtract k
5/3 x - k = cb +k-k
5/3 x - k = cb
Divide by c
(5/3 x - k)/c = cb/c
(5/3 x - k)/c =b
