Answer:
8
Step-by-step explanation:
Option A : a+o = 92 , 4a+2o = 284 is the right answer
Step-by-step explanation:
Let o be the number of oranges sold on Friday and
a be the number of apples sold on Friday
So,
A total of 92 was sold on Friday will yield the equation

On Saturday,
4 times the number of apples = 4a
2 times the number of oranges = 2o
So,

Hence,
The system of equations is:

Option A : a+o = 92 , 4a+2o = 284 is the right answer
