Let x = adults
Let 2x = students
Add together and set equal to the total number.
Just multiply my friend. The answer is 196
Given:
initial amount deposited = $2,520
final amount acquired = $2,850
number of years = 2 years
Use the formula from economics,
F = P (1 + i)^n
2,850 = 2520 (1 + i)^ 2
solve for i
i = 6.3% per year <span />
3/x-3+x/x+3
3(x+3)+x(x-3)/(x-3)(x+3)
3x+9+x^2-3x/(x-3)(x+3)
x^2+9/X^2-9
