According to the given data we have the following:
The price of 4 citrons and 3 fragrant wood apples=50 units
The price of 3 citrons and 4 fragrant wood apples=48 units
In order to find the price of a citron and the price of a wood apple we would formulate a system of equations:
So, let x=citrons
let y=wood apple
Hence:
1) 4x+3y=50
2) 3x+4y=48
Multiply equation 1 with 3, multiply equation 2 with -4
So:
12x +9y=150
-12x -16y=-192
-7y=-42
y=-42/-7
y=6
Substitute the value of y=6 in the original equation of 4x+3y=50
So, 4x +3(6)=50
4x+18=50
4x=32
x=32/4
x=8
Therefore, the price of a citron is 8 and the price of a wood apple is 6
