There is a $40 fee to rent a chain saw, plus $9 per day. Let x represent the number of days the saw is rented and y represent the charge to the user in dollars. If the total charge is $211 , for how many days is the saw rented?

The saw was rented for 19 days

Step-by-step explanation:

Given dа ta:

$40 fee for rentals plus $9 per day

Let x represent the number of days the saw is rented

y represent the charge to the user in dollars.

40 + 9x = y (equation from the question)

If total charge = $211

40 + 9x = 211

9x = 211 - 40 (grouping like terms)

9x = 171 (Making x the subject of the formula by dividing both sides by 9)

x = 19
