Answer:
y=25x+50
Explanation:
The rental rate for a power washer has a one time fee of $50 plus $25 for each day of the rental.
let x be day of rental n y be the total cost of rental
with 0 day (x=0), the one time fee means y=50 which is the y-intercept
$25 per day means the slope is 25
combining y = 25x + 50
