For a ride on a rental scooter, John paid an $8 fee to start the scooter plus 6 cents per minute of the ride. The total bill for
enot [183]

The linear equation is 8+0.06x=19.94 and John rode the scooter for 199 minutes.

Fee to start the scooter = $8.

Fee to ride per minute = 6 cents = $0.06.

Total bill = $19.94.

Let x be the minutes for which he rides the scooter.

The linear equation is formed as:

8+0.06x=19.94

0.06x=19.94-8

0.06x=11.94

x=199 minutes.

So, John rode the scooter for 199 minutes.

Elden [556K]

Answer:

40 + 2r

Step-by-step explanation:

Well an hour has 60 minutes.

So 60 x 1/30 = 60/30 = 2 minutes for each person that didn't get into the job

60 x 1/3 = 60/3 = 20 minutes for the people that made it into the job.

20 x 2 = 40 minutes in total for the people that made it into the job.

We don't know how much people got rejected so:

The answer is

40 + 2r
