Rashida owns a bike rental company. She charges an initial fee of $10 for each rental and an hourly rate of $4. A customer paid $34 for a bike rental. Which of the equations below could be used to find how many hours, x, the customer rented the bike?

$34 = 10 - 4x\\\\34 = 4 + 10x\\\\34 = 10 + 4x\\$

Answer:

$34 = 10 + 4x$

Step-by-step explanation:

Given:

Amount customer paid = $34

Initial fee = $10

Hourly rate = $4

We need to write the equation used to find how many hours, x, the customer rented the bike.

Solution:

Let the number of hours customer rented the bike be 'x'.

Now we can say that;

Amount customer paid is equal to sum of Initial fee plus Hourly rate multiplied by number of hours customer rented the bike.

framing in equation form we get;

$34 =10+4x$

Hence The equation used to find number of hours customer rented the bike is $34 =10+4x$ .

Answer:

Velocity (against wind) = 1,890 / 3 = 630 mph

Velocity (with the wind) = 1,890 / 2.5 = 756 mph

Plane speed (still air) = 630 + wind speed

Plane speed (still air) = 756 - wind speed

Adding both equations equals

2 * Plane speed (still air) = 1,386

Plane Speed = 693 mph
