---
The number of calories K needed each day by a moderately active man who weighs w kilograms, is h centimeters tall, and is a years old can be estimated by the formula
K = 19.18w + 7h - 9.52a + 92.4
A) Marv is moderately active, weighs 97 kg, is 185 cm tall, and is 55 yr old. What are his caloric needs?
B) Solve the formula for a; for h; for w.
P = 2l + 2w  and  w =  - l
   Are equivalent formulas involving the perimeter P, the length l, and the width w of a rectangle.  Devise a problem for which the second of the two formulas would be more
useful.
