Final answer:
Solving the proportion yields the approximate amount of muscle, which is 280.1 lbs.
Step-by-step explanation:
To calculate the amount of muscle a tiger has, we can use the given ratio.
The ratio states that for every 8 lbs of body weight, a tiger has approximately 5.2 lbs of muscle.
So, we can set up a proportion to find the amount of muscle in a 428 lb tiger:
8 lbs / 5.2 lbs = 428 lbs / x lbs
Cross multiplying, we get:
8x = 5.2 * 428
Dividing both sides by 8, we find:
x = (5.2 * 428) / 8
Therefore, a 428 lb tiger has approximately 280.1 lbs of muscle.
