I can't figure out how to do this problem. Any help would be greatly appreciated!

The target weight w for an adult man of medium build is:
w(h)=0.0728h^2 - 6.986h + 289 where h is in inches and w is in pounds.
Find the target weight of an adult man of medium build who is 72 inches tall.

Hi cam_ddrt,

Use simple substitution.

$w(72)=0.0728(72)^2-6.986(72)+289$
