Oceanside Bike Rental shop charges a 14 dollar fixed fee plus 9 dollars an hour for renting a bike. Sara paid 77 dollars to rent a bike. How many hours did she pay to have the bike checked out?

7 hours

Step-by-step explanation:

We have that the value of the review of a bicycle has the following function:

v = 14 + 9 * t

where t is the time in hours

if we know that Aara paid a total of 77, that is v = 77, we can calculate the value of t, replacing:

77 = 14 + 9 * t

solving for t:

t = (77 - 14) / 9

t = 7

that is to say that Sara left the bicycle in a total of 7 hours

i think is 3 and 6. this took me 10 min to think.hope to and hope that my answer is brainliest.(follow me )

the discriminant is 64 + 4*1*12 = 112

this is prime.
