y varies jointly with x and the square of n. When y = 25, x = 3 and n = 4. Find the value of y when x = 5 and n = 10. Round to the nearest whole number.

Question

If y varies jointly with x and the square of n, that means

$$y = kxn^2$$ where $k$ is a constant.
Plug in the known values of $x,y, n$ to find the value of $k$.  Then plug that value of $k$ into the formula to find $y$ when $x=5, n = 10$.
