Formulate an equation to calculate a person's estimated body weight.
Height = 5 ft 7 in, Age = 24
There are many different ways to estimate body weight, but one commonly used formula is the Devine formula: 

Body weight (in kg) = 50 + (0.91 x (Height in cm - 152.4))

In your case, the height is 5 ft 7 in which is equivalent to 170.18 cm. Substituting this value into the formula, we get the estimated body weight calculation:

Body weight (in kg) = 50 + 0.91(170.18 - 152.4) 
                   = 50 + 0.91(17.78)
                   = 50 + 16.18
                   = 66.18 kg

Please note that this equation only accounts for height and not for variables like age, muscle mass, and body fat percentage.
