City scooters charges customers by the minute to rent an electric scooter. Jana rented a scooter for $60 minutes and paid $9. Write an equation that shows the price to rent a scooter for any number of minutes

The price of the scooter rental is $0.15

A: x=9y
B: y=9x
C: x=0.15y
D: y=0.15x

The option D) y = 0.15x is the equation that shows the price to rent a scooter for any number of minutes.

Step-by-step explanation:

City scooters charges customers by the minute to rent an electric scooter.

It is given that,

The price of the scooter rental is $0.15 per minute.

⇒ 1 minute = $0.15

Jana rented a scooter for $60 minutes.

⇒ 60 minutes = 0.15 × 60

⇒ $9

To frame an equation that shows the price to rent a scooter for any number of minutes :

Let us take,

The variable 'y' as the total price.

The variable 'x' as the number of minutes for rental.

⇒ Total price = price of rent per minute × any number of minutes.

⇒ y = 0.15 × x

⇒ y = 0.15x

∴ The option D) y = 0.15x is the equation that shows the price to rent a scooter for any number of minutes.

y=0.15x

Step-by-step explanation:

Let p be the number of pens and let n be the number of notebooks.

4 notebooks + 3 pens cost $96 so 4n + 3p = 96

2 notebooks + 2 pens cost $54 so 2n + 2p = 54

We find n and p by solving the system of linear equations:

4n + 3p = 96

2n + 2p = 54

4n + 3p = 96

4n + 4p = 108 (we multiply this by 2 to cancel out 4n in both equations)

We then subtract the two equations:

(4n + 3p) - (4n + 4p) = 96 - 108

-p = -12

p = 12

So, a pen costs 12 dollars. We can use p to find n. We substitute 12 for p in one of our earlier equations:

2n + 2p = 54

2n + 2(12) = 54

2n + 24 = 54

2n = 30

n = 15

So, a notebook costs 15 dollars and a pen costs 12. Now, we need to find the cost of 8 notebooks and 7 pens:

8n + 7p = ?

8(15) + 7(12) = ?

120 + 84 = 204.

Thus, 8 notebooks and 7 pens cost 204 dollars (why is it so expensive lol).
