Us with this problem? ? it’s question b.

I'm going to use x in place of the word NOW to make things shorter

So we have 0.01x + x - 0.009x on the right side

We can factor out x to get (0.01 + 1 - 0.009)x

Combine like terms in the parenthesis and we have things simplify to this expression: 1.001x
This is because 0.01 + 1 - 0.009 simplifies to 1.001

The last thing to do is to replace the x with NOW and we end up with the simplified equation of
NEXT = 1.001*NOW
which is the final answer
