Two mechanics worked on a car. The first mechanic charged $95  per hour, and the second mechanic charged $60  per hour. The mech
Yanka [14]

Answer:

<em>Mechanic A worked for 5 hours</em> and <em>Mechanic B worked for 15 hours</em>

I hope my answer and explanation helped!

<u>okay to get started you need to make a system of equations:</u>

x= number of hours worked by mechanic A

y= number of hours worked by mechanic B

x + y= 20

95x + 60y= 1375

<u>substitute in an equation:</u>

x + y= 20

y= 20- x

95x + 60(20-x)=1375

<u>Solve for x</u>

95x + 1200 - 60x=1375

35x =175

x= 5

<u>plug in x to solve for y</u>

x + y= 20

5 + y= 20

y=15

<u>Check work</u>

then you're done :D

Mila [183]

Answer:

C. 0.1

Step-by-step explanation:

The sum of the probabilities of all possible events must equal 1.

Since there is no probability of purchasing two vehicles ore more, the events are:

- Purchase a new vehicle (0.5)

- Purchase a used vehicle (0.4)

- Purchase no vehicle at all (x)

The probability of not purchasing a vehicle is:

x=1-0.5-0.4\\x=0.1

The probability that you purchase no vehicle at all is: C. 0.1
