Answer:
one french fry is worth 2 and one hamburger is equal to 5
Step-by-step explanation:
if three fries add up to 30 then each fry is worth 10. if one fry and two burgers add up to 20 then 20-10=10, 10 divided by 2 equals one hambrger is equal to 5. and lastly 9-5=4, 4 by 2=2 so each fry is worth 2.
