Help please!! Thanks

Q2 2010

Step-by-step explanation:

Let the number of quarters = x

Samsung increases by 6 each quarter.

Apple decreases by 1 each quarter.

Samsung

L = a + (x - 1)*6

a = 1

L = 1 + (x - 1)*6

Apple

L = a - (x - 1)*1

a = 53

L = 53 - (x - 1)*1

Now the problem is how many quarters go by until they meet?

1 + (x - 1)*6 = 53 - (x - 1)                         Remove the brackets

1 + 6x - 6 = 53 - x + 1                             Combine like terms on both sides.

-5 + 6x = 54 - x                                     Add 5 to both sides

6x = 59 - x                                              Add x to both sides

7x =  59

x = 59/7 = 8 3/7

So sometime in the 8th quarter from zero they will be equal. At the end of the quarter, Samsung will be greater than Apple

So the answer should be 4 quarters from Q2 2009 or Q2 2010
