Answer: y = 25x + 50

Explanation: the total cost if the rental is a linear function of the number of days of the rental (x). Each day costs $25, so that is the slope of the line. Since there is also a one-time fee, independent of the number of days, this amount $50 represents a vertical shift of the line on the graph, by 50. y=25x+50 is an algebraic expression of that.

Answer:

y = 25x + 50

Step-by-step 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
