Answer:
She can buy 11 tokens
Step-by-step explanation:
8/4.40=x/6.05 (i set this up as a proportion. tokens/price=tokens/price)
4.40x=48.8 (cross multiplied)
x= 11 (divided both sides by 4.40)
16x + 9 = 9y-2x Add 2x to both sides
18x + 9 = 9y Divide both sides by 9
2x + 1 = y Switch the sides to make it easier to read
y = 2x + 1
It’s probably most definitely the third one but I really don’t know.
