Answer:
x = 61, y = 29
Step-by-step explanation:
29+x = 90
x = 61
x + y = 90
y + 61 = 90
y = 29
If x represents the number of students from country C.
then 122% of x = 116,000
122/100 * x = 116000
Transposing the formula for x;
therefore x = 116000 * 100/122 = 95,082 students
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
