Question 1078161: Latrice and Meagan are collecting coins. Latrice doubled her coin collection the first month, and then added 200 coins to her collection the second month. Meagan added 85 coins to her collection the first week, and then doubled her total the second week. Now Latrice and Meagan have the same number of coins. Did they begin with the same number of coins? Explain.

If each started with the same number of coins, x, then x must be a WHOLE NUMBER ( x must be positive and integer).

Latrice would have 2x%2B200 coins.
Meagan would have x%2B85%2B%28x%2B85%29 coins.

The description states that these coins counts were equal.
2x%2B200=x%2B85%2B%28x%2B85%29

Will this equation when solved show that x is a whole number?

.
Let assume that Latrice started with L coins, while Megan started with M coins.


Then after 2 weeks Latrice has 2L + 200 coins, while 

                   Megan has 2*(M+85) coins, as the condition says.


Also, the condition says that after two weeks 

2L + 200 = 2*(M+85).

It is equivalent to 

L + 100 = M + 85,   or   M - L = 15.

It means that the two girls started with DIFFERENT numbers of coins.

SOLVED.


        The solution by "josgarithmetic" is  TOTALLY  and  ABSOLUTELY   WRONG.

      After getting my notice, "josgarithmetic" quickly and quietly modified his solution.

      But what remained in his post is still out the logic.

Hey, "josgarithmetic",

I just asked you many times: what are you doing in this forum ?

Do you understand that you perform a role of a "local town idiot" in the forum ?

You are not able NEITHER solve correctly the problems, NOR explain the solutions in a way how it should be done . . .

Do you understand that when you appear here in the forum, you simple steel the opportunity from other tutors to do their work
in a way as it should be done ?

What is even worst, you steel the opportunity from students to learn on how to solve the problems correctly and to get
correct explanations.


I perfectly understand that there are problems there you can do something useful.
These problems are on line equations, intercepts, completing the square . . .

Work in this area and do not go across these borders to other areas where you are not an expert.

Nobody will touch you.

But if you will write in other subjects, I will criticize you every time you are wrong.

Do you understand me perfectly ?


If not, I will ask the supervisors of the forum to EXCLUDE you from the forum.


"josgarithmetic", GO AWAY FROM THE FORUM !
