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

The answer would be 27 because assuming that each package has 1 bar of soap and 1 tube of toothpaste, after 27 packages they would run out of toothpaste

It's like discovering the answer to a puzzle. the purpose in solving an equation is to find the value or values of the variable that makes it a true statement. any value of the variable that makes the equation true is called a solution to the equation.
