In the question it is stated that ,

1.2x = 84000 .

Therefore x = 84000/(1.2) = 70000.

Hence option A is the answer. :)

Let total payroll expense in year X be X.

Total payroll expense in year Y was $84000, that is ; 20% more than year X = 120% of X

120% of X = $84000

\(\frac{120}{100}\) * X = 84000

X = \(\frac{84000 * 100}{120}\) = $70,000

Answer A...

So I know the OA is A. $70,000. But I am getting $67,200.

Method I followed was:

20% of 84000 = 16800

84000+16800 = 67200

Where am I going wrong?

C. $64,000
D. $60,000
E. $52,320


In year \(X\) TPE was \(x\).
In year \(Y\) it was \(20\)% more \((1.2x)\) and equaled \(84000\).

So, \(1.2x=84000\)
\(x=70000\).

Answer: A

Letting p = the payroll expense in year X, we have:

1.2p = 84,000

p = 70,000

Answer: A
