The formula to approximate the hieght (h) of a male, in inches, is shown below, where t is the length of the tibia bone, in inches.

h=2.4t+32.2

Paul's height is 69.4 inches. What is the approximate length, in inches, of paul's tibia bone?

69.4 = 2.4t + 32.2

Solve for t.

2.4t=69.4+32.2

No.

In this step, you need to subtract 32.2 from each side of the equation.

You still haven't found the length of the tibia bone.

Good heavens! Paul's tibia is over 3 feet long! He must be a giant, yet he's less than 6 feet tall.

What did you miss in this problem?
