Answer: There are 152 apples.
The explanation is shown below:
- You need to write the following three equations, where
is the the number of apples,
is the number of pears and
is the number of oranges:
1) ![a+p=184](https://tex.z-dn.net/?f=a%2Bp%3D184)
2) ![a+o=248](https://tex.z-dn.net/?f=a%2Bo%3D248)
3) ![o=3p](https://tex.z-dn.net/?f=o%3D3p)
- You must substitute the equation 3) into the equation 2):
![a+3p=248](https://tex.z-dn.net/?f=a%2B3p%3D248)
- Now, you need to solve for
in the equation 1) and then you must substitute it into
:
![p=184-a](https://tex.z-dn.net/?f=p%3D184-a)
![a+3(184-a)=248](https://tex.z-dn.net/?f=a%2B3%28184-a%29%3D248)
- Solve for
, as following:
![a+552-3a=248\\-2a=-304\\a=\frac{-304}{-2}\\a=152](https://tex.z-dn.net/?f=a%2B552-3a%3D248%5C%5C-2a%3D-304%5C%5Ca%3D%5Cfrac%7B-304%7D%7B-2%7D%5C%5Ca%3D152)
- Therefore, there are 152 apples.
2000 x 2 x 0.02 = 80
answer
interest will be $80
