Answer:

159 minutes

Step-by-step explanation:

y = .11x + 3

$3 initial fee to start the scooter

$0.11 per minute

y = the total bill price of the scooter ride

x = the total minutes of the ride

plug in what we know : $20.49 for the whole ride

20.49 = 0.11x + 3

SOLVE !! 20.49 - 3 = 0.11x

17.49 = 0.11x

17.49 / 0.11 = x

x = 159 minutes

check answer if you want

20.49 = 0.11 (159) + 3

20.49 = 17.49 + 3

20.49 = 20.49
1) what do we know:
— total amount =$20.49
— flat fee = $3
— price per minute = $ 0.11

2) what we don’t know:
— how many minutes that the scooter was ridden? = X

3) set up the equation:
$3 + .11(x) = $ 20.49

4) isolate the variable x:
.11x = 20.49-3
= .11x = 17.49; x= 17.49/.11
X = 159

5) what does 159 mean (put in context) — it means 159 minutes or 2 hrs and 39 minutes.

6) fact checking = $3 + .11(159) = $20.49
= 3 + 17.49 = 20.49

OR

Take 20.49 - 3 = 17.49; divide 17.49 by .11 = 159.
