Best Rentals charges a daily fee plus a mileage fee for renting its cars. Barney was charged $123.00 for 3 days and 300 miles, while Mary was charged $216.00 for 5 days and 600 miles. What does Best Rental charge per day, for mileage?

Let x = daily fee and y = mileage fee. The system of equations would then be as follows: Barney (3x + 300y = $123.00), Mary (5x + 600y = $216.00).

We take Barney's equation and isolate for x:

300y = 123 (3x + 300y)/3 = 123/3 x + 100y = 41 x = 41-100y

There were 44,000 people at a ball game in Los Angeles. The day's receipts were $369,000. How many people paid $13.00 for reserved seats and how many paid $6.00 for general admission?
Let x = people with reserved seats and y = people with general admission. This means that x + y =…
