Answers:
a. 0.5 people
b. 10 spring rolls will serve 5 people, 16 spring rolls will serve 8 people, 25 spring rolls will serve 12.5 people
c. n/2 or 1/2 of n
Step-by-step explanation:
if 6=3p, p representing each person, then we find that 2 spring rolls serve 1 person, so 1 spring roll serves 0.5 people!
if 1=0.5p, then p is 1/2 of the amount of spring rolls.
Divide each of the amount of spring rolls by 2.
10=5p
16=8p
25=12.5p
n=n/2
The variable p is important, as to show that it's the amount of people.
Hope this helps!

<u>Answer:</u>

<u>Explanation:</u>
We are given product of two consecutive odd integers is equal to 72.
Let one integer be x , then since these are consecutive and odd so the other integer will be equal to x + 1.
Their product is equal to 72. So,
x * (x + 1) = 72
=> 
=>
is the required quadratic equation.
Answer:
Return on investment (ROI) = 7%
Step-by-step explanation:
Given:
Amount invested = $10,000
Total amount get (refund) = $10,700
Find:
Return on investment (ROI) = ?
Computation:
Amount Return = Total amount get (refund) - Amount invested
Amount Return = $10,700 - $10,000
Amount Return = $700
![Return\ on\ investment \ (ROI) = [\frac{Amount\ Return}{Amount\ invested} ]100\\\\Return\ on\ investment \ (ROI) = [\frac{700}{10,000} ]100 \\\\ Return\ on\ investment \ (ROI) =7](https://tex.z-dn.net/?f=Return%5C%20on%5C%20investment%20%5C%20%28ROI%29%20%3D%20%5B%5Cfrac%7BAmount%5C%20Return%7D%7BAmount%5C%20invested%7D%20%5D100%5C%5C%5C%5CReturn%5C%20on%5C%20investment%20%5C%20%28ROI%29%20%3D%20%5B%5Cfrac%7B700%7D%7B10%2C000%7D%20%5D100%20%5C%5C%5C%5C%20Return%5C%20on%5C%20investment%20%5C%20%28ROI%29%20%3D7)
Return on investment (ROI) = 7%
