The amplitude is 1/2.
Answer:
y = 15x
Step-by-step explanation:
The equation for direct variation is ...
y = kx
where k is the constant of proportionality.
__
We can find k by dividing by x:
y/x = k
Using the given values, we find it to be ...
75/5 = k = 15
Using this value of k in the equation, we find the equation of direct variation is ...
y = 15x
This can be seen as a ratio of 2 numbers. It it says that 2/9 is the ratio of catchOfDay/totalLunches.
So:
2/9 = catchOfDay/totalLunches
It also says that the catchOfDay was ordered 24 times and we want to find totalLunches, represented by x.
So:
24/x = catchOfDay/totalLunches
Putting the 2 equations together we can conclude:
2/9 = catchOfDay/totalLunches = 24/x
simplifying would give a final answer of:
2/9 = 24/x
If we wanted to solve for x, we cross multiply to try and isolate the x and get:
2x = 24 * 9
divide both sides by 2:
x = 24 * 9 / 2
Working this out then we get:
x = 108
