Hi! I'm happy to help!
We need to calculate how many days we are at the airport, and then multiply it by the price per day.
We are there for part of Tuesday, but part days count as full days. We are there for Wednesday, Thursday, Friday, and part of Saturday. We are there for 4 days that cost $14, and one day that costs $8.
We can write our equation like this:
(14·4)+8
56+8
64
So, the the total cost of parking is $64.
I hope this was helpful, keep learning! :D
