Solve the formula for the indicated variable. Then use the supplied values to solve the equation.The relationship between the distance p from an object to a lens, the distance q from the image to the lens, and the focal length f (the distance from the lens to the principal focus) is given by 
Solve for f. What is the focal length when p is 726 mm and q is 24.2 mm? (All values are approximate.)
A. f = p + q = 750 mm
B. f =
