The base rate to rent a car is $75. then, the customer is charged $2.00 per mile for each mile driven over 200 miles. joel rented a car and drove 250 miles. if y = 2x + 75 models the function, which domain value gives joel's total rental cost?
a) x=50 b) x=100 c) x=200 d) x=250

The domain is going to be ur x valuey would be ur range
y = 2x + 75base rate is 75the x represents miles over 200.

So if he drove 250then he drove 50 miles overso ur domain (x) would 
be 50 <==

In other words, the first 200 miles, u r not charged for mileage. So if he only drove (anything under 200 miles), then he would just be charged the 75 dollar base rate
