Answer: We can use a system of equations to solve this problem. Let x be the number of oranges sold and y be the number of apples sold. Then we know that:
x + y = 15 (the total number of fruits sold)
1x + 2y = 25 (the total cost of the fruits sold)
We can use the first equation to solve for one variable in terms of the other.
For example, we can solve for x:
x = 15 - y
Now we can substitute this expression into the second equation:
1(15 - y) + 2y = 25
15 - y + 2y = 25
3y = 10
y = 10/3 = 3.333
We can round it to 3 apples sold
So we have 3 apples and 12 oranges sold.
This can be represented in a graph with a point (12,3)
Alternatively, we can solve for y:
y = 15 - x
Now we can substitute this expression into the second equation:
1x + 2(15 - x) = 25
1x + 30 - 2x = 25
-x = -5
x = 5
So we have 5 oranges and 10 apples sold.
This can be represented in a graph with a point (5,10)
Both solutions represent the same values, the number of oranges and apples sold, but represented in a different way.
