Answer:
step number 1 is incorrect.
Step-by-step explanation:
Here is the solution of this equation [2x-31-1=2].
2x-31-1=2
or 2x-31=2+1
or 2x=2+1+31
or 2x= 34
or x=34/2
or x= 17
the answer of this equation is X=17.

Since the percent increase is bigger than 100%, it definitely has to be more than 54,000.
so let's break this down:
250%= 100% + 100% + 50%
we know 100% is the whole price so if there are 2 100% we have to multiply the price by two!!!
54,000•2 = 108,000
now, 50% is half of the whole price, divide the price by two:
54,000÷2= 27,000
so add your results and you will get this!
108,000+27,000= 135,000
