An auto repair shop charges $50 plus $25 per hour for labor. Which type of equation is most suitable for modeling the cost of an auto repair? A) linear B) radical C) rational D) exponential

Linear Equation

Step-by-step explanation:

The equation would be y=25x + 50 which is linear. Radical expressions have a number under the radical sign which this equation doesn't. Rational expressions have fractions containing polynomials in the numerator and denominator and exponential equations have 'x' as the exponent in a function.
