Question

Help!!!
Three years ago, the average price of movie tickets was $8.75 and now it’s $10.87. What is the annual multiplier and percent increase? Sketch graph and make a table for the situation.

Answer 1

Answer:

Price of tickets:

3 years ago - 8.75  

now - 11

annual multiplier:

b³ = 11/8.75  

b = ∛11/8.75

b = 1.079

The annual multiplier is 1.079.

1.079 * 100% = 107.9%

107.9% - 100% = 7.9%

The percentage increase is 7.9%
