Multiply the bracket by -4
−4(3−1)+2
-12+4+2 : - negative sign and - negative sign = + positive sign
-12+6
= -6
Answer: -6
Since we add those together, we have to add the like terms. 2x and x are like terms and 5 and 3 are like terms as well, So now we have the equation of 3x+8
Integrating
gives

Notice that
forces all terms in the sum to be 0, so that

and hence

making the first option correct.
To set the equation,we can first find how much price would be raised within a year:
=500×(1+7%)
=500×1.07
As the years go by the increase would accumulate,and the equation would be:
