Question

Which statement describes the cost to park as a unit price?
Ari paid 1 quarter to park for 15 minutes at a parking meter.
Brianna paid 30 cents to park for 30 minutes at a parking meter.
Caesar paid 12 dollars to park for 1 day in the airport parking lot.
Deanna paid 70 dollars to park for 7 days in a city parking lot.

Answer 1

Caesar. He paid $12 to park for 1 day, which gives a unit price of $12 per day. The others give prices for multiple minutes or days (not directly a price per one unit).
