Answer:
The price of 1 packet of French fries, 1 cheeseburger, and one drink cost $5.55
Step-by-step explanation:
Let
x ----> the price of 1 packet of French fries
y ---> the price of 1 cheeseburger
z ---> the price of one drink
we know that
[tex]3x+2y+z=10.95[/tex] ----> equation A
[tex]x+2y+3z=11.25[/tex] ---> equation B
Adds equation A and equation B
[tex]3x+2y+z=10.95\\x+2y+3z=11.25\\------------\\3x+x+2y+2y+z+3z=10.95+11.25\\4x+4y+4z=22.2[/tex]
Divide both sides of the equation by 4
[tex]x+y+z=5.55[/tex] ----> equation C
The equation C means ----> The price of 1 packet of French fries, 1 cheeseburger, and one drink cost $5.55
