$\left( \frac{100+B}{100+M}\right)\times I$

Correct answer:

I. The expression that represents the number of babies born in 2002.

17,000I

II. The expression of the number of babies born per married couple in 2009.

$\left( \frac{100+B}{100+M}\right)\times I$

Explanation:

To identify,

I. The expression that represents the number of babies born in 2002.

Recall the given information in this particular question.

It is known that in 2002 there are 17,000 marriages and represents $\frac{\text{Babies}}{\text{Marriage}}$ .

Using this information to create a mathematical expression is as follows.

$17,000 \text{ marriages}\times \frac{\text{babies}}{\text{marriage}}\Rightarrow17,000 \text{ marriages}\times I=17,000I$

Now to identify,

II. The expression of the number of babies born per married couple in 2009.

Use the formula given

$\left(\frac{X_{new}-X_{old}}{X_{old}} \right )\times 100$

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,

$\left( \frac{100+B}{100+M}\right)\times I$

Correct answer:

I. Susan (12th Grade, Flute Solo)

II. James & Jimmy (10th Grade, Vocal Duo)

Explanation:

Recall the criteria for this particular problem.

Five musicians are scheduled to play each day. To feature the departments strengths, the majority of the musicians on one of the days will be composed of woodwind instruments (clarinets, flutes, saxophones, oboes, bassoons) and the other day will be primarily solo musicians.

Looking at day one it is clear that represents the woodwind day and day two represents the solo day.

Therefore, for someone to be able to play either day that student must play a woodwind instrument and be doing a solo. For a musician(s) to play neither day it must be a group that is composed of instruments other than woodwind.

Also recall that violins are string instruments, trumpets are brass instruments, and vocal is ones voice.

Keeping all of this in mind, the correct answer is,

I. Susan (12th Grade, Flute Solo)

II. James & Jimmy (10th Grade, Vocal Duo)
