Answer:
Step-by-step explanation:
Let the number of nickels is n, number of quarters is q.
<u>We know that:</u>
- Nickel = 5¢, quarter = 25¢, $2 = 200¢
<u>As per given we can set the following system:</u>
<u>Solving this we get:</u>
2.25+5.50, 2.50+5.25, 3.49+4.26, etc.
360 = 37.50x + 60
-60 on both sides
300 = 37.50x
/37.50 on both sides
8 = x
Answer:
x = 8
The first one is right and the third one is right, but you need to switch the 15% and the 95%.
In #2, it's asking for the kids that <em>are not</em> Michael, so it'd be 18/19. Which is then rounded to roughly 95%.
#4 asks for 6/40 = 15%
