Answer:
Use the formula for compound interest to determine the amount of money in each ... An investing group has $50,000 to invest. They put the money in an account that compounds interest ... How much money will the group have at the end of 10 years? 20. Interest is compounded quarterly at Money Bank at a rate of 5.5%.
I don't know if this helps

All you have to do in this question is apply the formula and use a calculator
2070(1-0.22)^4= 766.21 dollars ( the number has been rounded)
Can I see a picture of the problem?
(5x) / (2/11) = 3 / (1/5)
cross multiply
(5x)(1/5) = (2/11)(3)
x = 6/11
The <em><u>correct answer</u></em> is:
non-extraneous
Explanation:
An extraneous solution is one that we arrive at that will not work in the equation. For rational equations such as we have, extraneous solutions are ones that will cause the denominator to be 0. For ours, that would mean x=-5.
The equation we have is:
We will multiply everything by (x+5) in order to get that off the bottom of the fractions:
Multiply all terms by 5 to eliminate the fraction:
Combine like terms:
20+x = 10
Subtract 20 from each side:
20+x-20 = 10-20
x = -10
Since this is not -5, this is not an extraneous solution.
