Answer:
x=54.9363
Step-by-step explanation:
- x^2+7=55^2 square root and exponent cancel out
- x^2+7=3025 55*55=3025
- x^2=3018 subtract 7 from both sides
- x=√3018 take square root of both sides
- x=54.9363
Firstly, solve the effective annual interest (ieff) with the equation,
ieff = (1 + i/m)^m -1
where i is the interest rate and m is the number of times the interest is compounded in a year. In this problem, m is 12
Substituting the values,
ieff = (1 + 0.034/12)^12 - 1 =0.03453
To solve for the future (F) amount of the present investment (P),
F = P x (1 + ieff)^n
where n is number of years.
F = ($742) x (1 + 0.03453)^15
Thus, the answer is $1234.76.
