Step-by-step explanation:
Since we have given that
Number of green tickets =3
Number of yellow tickets = 4
Number of purple tickets = 3
Total number of tickets = 3+4+3=10
Now,
As we know that Pedro select a ticket and replace it and then select another ticket , total number of outcomes will never change it will be 10 only for each case.
Probability that he chooses a yellow ticket and then a purple ticket is given by

The equation is 36 - 4x = 6.
Solution:
To write the equation without fraction.


The denominators must be same to add/subtract the fractions.
LCM of 1, 9 and 3 = 9.
Multiply first term by
and
by
to make the denominator same.



Multiply by 9 on both sides.

Both 9 in the numerator and denominator get canceled.
36 - 4x = 6
This term does not have fraction.
Hence the equation is 36 - 4x = 6.

An easier way of doing this would be to subtract the initial attitude from the final attitude and divide by the rate of increase
= 30000 - 6000÷4000
= 24000÷4000
