Answer 1

Hi!

So, we're just going to work on plugging in the numbers to this formula.

BMI = Weight (in pounds) * 703 / [Height (in inches)]^2.

We have his weight and his height. With this information, we can properly answer the question.

To start off, we plug in his weight and height to their positions in the formula.

BMI = 130 * 703 / (72)^2.

Now that we have our formula filled up, we need to work on solving it. Whenever we're working in math, we always follow the order of operations, or, PEMDAS.

PEMDAS:

P: Parenthesis 
E: Exponents
M: Multiplication
D: Division
A: Addition
S: Subtraction

This handy little acronym tells us the order in which to perform operations. (Hence the name).

So, we start in the parenthesis. 

BMI = 130 * 703 / (72)^2

BMI = 130 * 703 / 5,184

Now we move down the list and work left to right. First, we'll multiply, and then lastly we'll divide. After we perform these operations, we'll have our answer.

BMI = 130 * 703 / 5,184

BMI = 91,390 / 5,184

BMI = 17.629243827 (repeats).

Our final BMI is going to be 17.6. 

Hopefully, this helps! =)
