There will be an estimated amount of 1125 faulty souvenir tokens.

Step-by-step explanation:

Hi!

So, let's do this problem out.

So we for every 400 tokens, 3 are faulty

Let's write that in a ratio

3:400

Ok, great!

So, now we know that:

3:400 = x:150,000

We can set up a percent proportion

[tex]\frac{3}{400} =\frac{x}{150,000}[/tex]

To find x, we do:

[tex]x=\frac{3*150,000}{400}[/tex]

[tex]x=\frac{450,000}{400}[/tex]

[tex]x=\frac{4,500}{4}[/tex]

[tex]x=1125[/tex]

There will be an estimated amount of 1125 faulty souvenir tokens.

Let me know if you have any questions.

Read the excerpt from an interview with Florence Griffith-Joyner.


WILL: I know that you dropped out of college in 1979 to help support your family. It seems like family must be very important to you.


FLORENCE GRIFFITH-JOYNER: Yes. Family is first in my life. It was a very difficult decision for me to drop out of college at that time. Growing up in poverty, I didn't have the financial support that I would have needed to go to college. I wasn't offered an athletic scholarship. I wasn't offered an academic scholarship. I thought, "How am I going to stay in school?" So I enrolled in school, and I thought, "I really want to run, but I know I have to concentrate on my academics as well." I tried a year of college, and I thought, "I can't continue because I have no financial support." I had to take the bus two hours to school, two hours back. The need was greater than what I could afford.


What is the purpose of the interviewer’s question?

A. to share Florence Griffith-Joyner's training techniques
B. to share Florence Griffith-Joyner's family recipes
C. to share Florence Griffith-Joyner's commitment to family
D. to share Florence Griffith-Joyner's favorite coach
