really need help review for my on wensday

Answer:
A is graph 3
B is graph 1
C is graph 2
Step-by-step explanation:
A is graph 3 because it’s says that she begins with at least a total of 80 os the y should not start at 0, instead it should, start at 80 but every time she gets a question wrong the graph keeps going down.
B is graph 2 because it States that Heath has 10 pennies to begin with so the y isnt 0 but 10 and every time she doubles it the graph only goes up.
C is graph 1 because it states that to Exeter a school fair it’s 5 bucks but each ticket cost 50 cents so it starts at 5 then keeps going up.
(I’m 100% sure of A but I’m not really sure about B and C but this is my best guess)
