Answer:
2 apples and 4 bananas
Explanation:
Given info:
- He bought $4 worth of apples and bananas.
- Each apple costs $1 and each banana costs $0.50.
- He bought a total of 6 apples and bananas altogether.
Question given:
Determine the number of apples, x, and the number of bananas, y, that Juan bought.
Solution:
Since, we know that;
apples = x
bananas = y
Cost of each apple = $1 & Cost of each banana = $ 0.50
Total = 6
The equation that represents the following information:
x + y = 6
x + 0.5y = 4
We can multiply the top equation by -1 so it becomes -x -y = 6
-x - y = 6
x + 0.5y = 4
Now, we can use elimination to cancel out the x.
-0.5y = -2
y = 4
Because y=4, x must be 2 since x+y=6. So,
x = 2 and y = 4
Which means;
Juan bought 2 apples and 4 bananas.
