Answer: The number of girls in the auditorium is represented by the algebraic expression y=(4x +72) /5
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
- <em>Number of boys added: 18
</em>
- <em>Ratio of boys to girls: 5:4
</em>
So, the total number of boys is:
x + 18
Number of girls = y
Number of boys / number of girls = 5/4
(x+18) /y = 5/4
Solving for "y"
4 (x +18) =5 y
4x +72 = 5y
(4x +72) /5 = y
The number of girls in the auditorium is represented by the algebraic expression y=(4x +72) /5

Answer:
C - 100% of 0.25
Step-by-step explanation:
This answer is basically the same as 25% of 100, just worded differently to confuse you.
25 is 1/4th of 100, so this should be the answer. :)
If you're curious of what the other answers amount to:
One hundredth of 250 = 2.5
50% of 5 = 2.5
40% of 1 = 0.4
