Galileo is currently renting a car that costs $20 per month. He is planning to buy a brand new car that costs $30 per month. If Galileo will have to pay for the new car for a year, how much will be the difference if he gets the brand new car instead of renting a car? Let's be accurate as possible.
Galileo pays $20 x 12 = $240 for renting a car every year. He will pay $30 x 12 = $360 for the brand new car for a year. Therefore the difference between a new car and a refurbished car is $360 - $240 = $120.
The answer: 120.
