Hello, can someone help me understand how answer to q1 is 17000/I ? Thank you

Recall the information given in the question.

We know that in 2002 there were 17000 marriages, and I represent \(\frac{Babies}{Marriage.}\)

Using the information, make a mathematical expression:

17,000 Marriages x babies/marriage = 17000 marriages x I = 17000I

­Use the formula given

\((\frac{X_{new}-X_{old}}{X_{old}})*100\)

This part of the problem is asking for a ratio, but the variables that are given are percents.

Therefore, the 100’s are there because M and B are percent quantities. They are both added because M is a negative number.

So the number in the numerator is the percentage of babies that exist in 2009 compared to 2002 (a number that will be less than 100). The denominator is the percentage of the 2002 marriages that exists in 2009 (a number greater than 100).

Thus the solution is,

\([\frac{100+B}{100+M}]×I\)­
