Fairview auto repair originally paid its mechanics $20 per hour. Now that there is a new owner, the mechanics make 5% less. How
sattari [20]

Answer:

The new amount paid to mechanics per after by new owner is $ 19 Answer

Step-by-step explanation:

Given as :

The amount paid to mechanics initially = $ 20 per hour

Now, The new owner paid less at the rate = 5%

Let the amount paid to the mechanics after 5 % less = x per hour

So, According to question

The new amount paid to mechanics per hour = initial amount paid per hour × ( 1 - \frac{rate}{100} )

or, The new amount paid to mechanics per hour =  $ 20 × ( 1 - \frac{5}{100} )

I.e The new amount paid to mechanics per hour =  $ 20 × 0.95

∴ The new amount paid to mechanics per hour =  $ 19

Hence The new amount paid to mechanics per after by new owner is $ 19 Answer

Tpy6a [65]

Answer:

Unless im being completely braindead right now there isn't a whole number that works with this. When simplified its 5/2 or 2.5 but because it isn't an actual whole number (like 2, 4 and 6) they don't count.
