Skippy should invest $ 7500 in account offering 4 % interest and $ 2500 in account offering 8 % simple interest
<em><u>Solution:</u></em>
Given that Skippy has a total of $10,000 to split between two investments
One account offers 4% simple interest, and the other account offers 8% simple interest
Total interest earned = 500
Number of years = 1
Let the principal with rate of interest 4 % is x
So the principal for rate of interest 8 % is 10000 - x
Total interest earned = simple interest for 4 % interest + simple interest for 8 % interest
Simple interest is given as:
![S.I = \frac{pnr}{100}](https://tex.z-dn.net/?f=S.I%20%3D%20%5Cfrac%7Bpnr%7D%7B100%7D)
Where "p" is the principal and "r" is the rate of interest and "n" is the number of years
Therefore,
![\text{ Total interest earned } = \frac{x \times 1 \times 4}{100} + \frac{10000-x \times 1 \times 8}{100}](https://tex.z-dn.net/?f=%5Ctext%7B%20Total%20interest%20earned%20%7D%20%3D%20%5Cfrac%7Bx%20%5Ctimes%201%20%5Ctimes%204%7D%7B100%7D%20%2B%20%5Cfrac%7B10000-x%20%5Ctimes%201%20%5Ctimes%208%7D%7B100%7D)
![500 = 0.04x + (10000 - x)0.08\\\\500 = 0.04x + 800 - 0.08x\\\\-300 = -0.04x\\\\x = 7500](https://tex.z-dn.net/?f=500%20%3D%200.04x%20%2B%20%2810000%20-%20x%290.08%5C%5C%5C%5C500%20%3D%200.04x%20%2B%20800%20-%200.08x%5C%5C%5C%5C-300%20%3D%20-0.04x%5C%5C%5C%5Cx%20%3D%207500)
Therefore skippy should invest $ 7500 in account offering 4 % interest
And skippy should invest (10000 - x) = (10000 - 7500) = $ 2500 in account offering 8 % interest
Answer:
number of members in 2006=190
230members on 2010
Step-by-step explanation:
2008-2006=2
20*2+150= 190 ans (1)
b)
20x+150=230
20x=230-150= 80
x= 80/20=4---ans (2)
