Answer:
$500
Step-by-step explanation:
Consider the values shown, what you should notice is that the ratio remains the same as you would expect;
The money per raffle sold will be the same ordinarily so this is recognisable logically;
The first pair of corresponding x and y values are 5 and 25, representable as the ratio:
5 : 25
Which simplifies to (by dividing each part of the ratio by 5):
1 : 5
The second pair is 15 and 75:
15 : 75
Which simplifies to (by dividing each part of the ratio by 15):
1 : 5
The same applies to the third pair (by dividing each part of the ratio by 25)
This translates to 1 raffle raising $5;
We want to find y when x = 100;
If we use the ratio, we can find out how x and y values are related;
The way to understand this is think what do we multiply or divide the left number (x part of the ratio) to get the number on the right (y part of the ratio);
Well, 1 multiplied by 5 would give 5;
This means y = 5x;
So, if x = 100, then:
y = 5(100)
y = 500
