Question

r a ride on a rental scooter, ivan paid a 5$ fee to start the scppter plus 9 cents per minute of the ride. the total bill for ivan fide was 11.39. for how many minutes did ivan ride the scooter?

Answer 1

So the equation we could use is y = 0.09x + 5 because the rate per minute (x) is 9 cents and the starting value (y-intercept) is 5 dollars.
If you know that the total bill (end y value) is 11.39 dollars, then you can put 11.39 instead of y to get 11.39 = 0.09x + 5.
Then solve for x by subtracting 5 from both sides to get 6.39 = 0.09x, then divide both sides by 0.09 to get 71. Since x is the number of minutes, we found that he rode the scooter for 71 minutes
