Answer:
225
Step-by-step explanation:
1200 divided by 225=3
First, distribute the 3 into (-4z+5w):
3w+12z-15w+4z
Combine like terms:
3w-15w+12z+4z
-12w + 16z
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
If you need to find the unit rate of just one pound you can just divide. 8.43 divided by 3. You would get 2.81 so it would cost $2.81 for just one pound. I hope this helps!
The correct equation that models for this problem is x over y or x/y.
Let the following values be:
x - would be the money or commissions that Duncan earned.
y - would be the 20 percent that he gives his assistant
