Given:

Consider the complete question is "Patty and carl went to the movie. Patty bought two tickets for 7.35 each. Carl bought two buckets of popcorn at 5.60 each. How much more money did patty spend than carl?".

To find:

How much more money did patty spend than carl?

Solution:

We have,

Price of 1 ticket = 7.35

Price of 1 bucket of popcorn = 5.60

Using the given information, we get

Price of 2 ticket = 2(7.35) = 14.70

Price of 2 bucket of popcorn = 2(5.60) = 11.20

Now, difference between the amounts spend by patty and carl is

Therefore, patty spend 3.50 more than carl.
