Where W = one’s weight in pounds, and H = one’s height in inches.

17<BMI<22

17<703W<22 this is an equivalent inequality replacing BMI with the formula H2

17<703W<22 H2 is replaced by the height in inches 65.52

17<703W < then you multiply all three of the terms by the denominator 65.52

17(4290.25) < 703W (4290.25) < 22(4290.25) the canceling has been done 4290.25

72934.25 < 703W < 94385.5 the multiplication has been done also

72934.25 < 703W < 94385.5 the terms has been divided and the W has been isolated

703 703 703

104 < 134

It is assumed that the persons that are 65.5 inches might have a longer life span if they are at the weight of about 104 pounds and 134 pounds. Now the second inequality formula for W has to be solved, before W can be plugged into find the value of W.

23< 703 < 25 first multiply all the terms by H2 to take away the denominator H2

23 H2 < 703W < 25 H2 divide all terms to get 703 isolated and W

23 H2 < W <25 H2 this is equivalent inequality to solve the second weight interval

I will plug in the height squared (4290.25) <W< 25 (4290.25) multiply these terms by the squared. This will help me to find out what the second
