I believe the correct answer is: 37%
Use the given values in the compound interest formula to solve for time, n.
A is the final amount of money, $2800
P is the initial or starting amount $1900
i is the interest rate as a decimal 0.025
n is time in years since it annual.
2800 = 1900(1 + 0.025)^n
2800 = 1900(1.025)^n
2800/1900 = (1.025)^n
28/19 = (1.025)^n
take the natural log of both sides to solve for exponent.
ln(28/19) = ln(1.025^n)
power rule of logarithmic moves exponent
ln(28/19) = n*ln(1.025)
ln(28/19) / ln(1.025) = n
put into a calculator
15.7 years = n
*your
If the ratio is 5:3, then you divide 275 by 5, and then multiply it by 3. If you test the result, you'll find that the ratio fits.
Hey there!
10(a - 2.5 + 0.56b)
= 10(a) + 10(-2.5) + 10(0.56b)
= 10a - 25 + 5.6b
= 10a + 5.6b - 25
Therefore, your answer is: 10a + 5.6b - 25
Good luck on your assignment and enjoy your day!
