The first answer in Question A is Business Plan and the second answer is $3 less.
The first answer in Question B is 12 and the second answer is Residential Plan.
I think is
4x - 3 (-2) = 18
4x + 6 = 18
4x = 12
x = 3
565 sheets/ 1 book* 2,000 books= 1,130,000 sheets.
The final answer is 1.13*10^(6) sheets.
Hope this helps~
