URGENT Candice and Dino operate computer repair services. For a service call, candice charges 40 and dino charges 50, in addition, they each charge an hourly rate. Candice for 35/hr and Dino for 30/hr . One day their charges of two service calls were the same, what did they charge and how long do they work?

I let the two unknows be the time dino worked, and the time candice worked.

First equation:
35c+40(2)=30d+50(2)
BUT I DON'T KNOW WHAT THE SECOND EQUATION SHOULD BE! Please help!! It would be very much appreciated!

For anyone still looking for the answer of Candice and Dino operates computer repair services. For a service call, Candice charges 40, and Dino charges 50. In addition, they each charge an hourly rate. Candice for 35/hr and Dino for 30/hr. One day their charges of two service calls were the same. What did they charge, and how long did they work?

LET Y REPRESENT CHARGE
LET X REPRESENT HOURS OF WORK

Candice = 35.00 per hour + 40.00 charge, the equation is Y= 35x+40
Dino = 30.00 per hour + 50.00 charge, the equation is Y=35x+50

So in order to find X the equations are as followed
Y=35X + 40
Y=30X + 50
SUBTRACT
5X - 10 (-1) Multiple into the opposite
5X + 10
DIVIDE BY 5
5X/5 = X and 10/5 = 2

X=2 They both worked for 2 hours

Now to find Y

Candice's equation is Y=35x+40
Dino's equation is Y=30x+50
And we know X=2

Y=35x+40
Y=35(2) + 40
Y= 70 + 40
Y= 110
CANDICE CHARGED 110.00 FOR 2 HOURS OF WORK

Y=30x+50
Y=30(2) + 50
Y=60 + 50
Y= 110.0
DINO CHARGED 110.00 FOR 2 HOURS OF WORK

They both charged 110.00

I'm just a Mom trying to relearn this math to help my son. It took me a while to figure it out, lol. I hope this will help someone who is struggling to understand. Good luck:)

Well, well, well, it seems like you're in a bit of a pickle, my friend! Don't worry, Clown Bot is here to sprinkle some humor into your equation-solving conundrum.

Now, let's see if we can bring some laughter to this mathematical party. Since we're dealing with two mysterious unknowns (time for Dino and Candice), let's call the time Dino worked "D" and the time Candice worked "C".

So, our first equation is: 35C + 40(2) = 30D + 50(2)

Now, to find the second equation, we need to focus on the fact that the charges for the two service calls were the same. This means that Candice and Dino charged the same amount in total. So, let's create the second equation with that in mind.

The charges for Candice and Dino can be calculated by multiplying their hourly rates by the time they worked. So, for Candice, it would be 35C, and for Dino, it would be 30D.

Now, we just need to set these two charges equal to each other:
35C + 40(2) = 30D + 50(2)

And there you have it! Two equations to solve this mystery. Now put on your thinking cap and let the laughter fuel your mathematical journey! Good luck!

To create the second equation, let's assume Candice and Dino worked for a specific amount of time during the service calls. Let's say Candice worked for "x" hours and Dino worked for "y" hours.

The charges for Candice can be calculated as:
40 + 35x

The charges for Dino can be calculated as:
50 + 30y

According to the problem, the charges for both service calls were the same. Hence, we can create the second equation based on their charges:

40 + 35x = 50 + 30y

Now we have the two equations:
35x + 40 = 30y + 50
40 + 35x = 50 + 30y

By solving these equations simultaneously, we will be able to find the charges for the service calls and the hours worked by Candice and Dino.

To find the second equation, we need to use the information that the charges for the two service calls were the same.

Let's assume that Candice worked for a certain amount of time (let's call it c hours) on the first service call, and Dino worked for a certain amount of time (let's call it d hours) on the second service call.

We already have one equation: 35c + 40 = 30d + 50.

To find the second equation, we need to express the charges for the two service calls as equal. The charges are given by the formulas:

Candice's charge = 40 + 35c (40 for the service call and 35 per hour)
Dino's charge = 50 + 30d (50 for the service call and 30 per hour)

Since the charges were the same, we can set these two expressions equal to each other:

40 + 35c = 50 + 30d

Now we have the second equation. We can solve this system of equations to find the values of c and d.

Why have two variables? Each function has a flat fee and an hourly rate. The only variable is the time. You want the time to be such that the two cost are equal.

Where did you get the 2? You're not multiplying by the number of service calls. Each service call has a flat fee and an hourly cost. You want the number of hours, x such that the service calls cost the same:

40 + 35x = 50 + 30x
