Respuesta :
Multiply the amount per mile by number of miles, use x for the number of miles. Then add the fee to that to gets the total (y).
Answer: y = 3x + 75
Answer:
- y = 3x + 75
Step-by-step explanation:
Slope-intercept form:
- y = mx + b, where m- slope, b - y-intercept
The flat rate charge is the y-intercept:
- b = 75
The charge per mile is the slope:
- m = 3
Substitute the values to get the equation:
- y = 3x + 75
