I'v done the work and used a calcultor, but the answer just does not make sense, the problem is 1/4 of 3,500, what is your answer?
$$\left({\frac{{\mathtt{1}}}{{\mathtt{4}}}}\right){\mathtt{\,\times\,}}{\mathtt{3\,500}} = {\mathtt{875}}$$
does that make sense to you ?
1/4 = 2.5 (25) (25%)
$${\frac{{\mathtt{4\,000}}}{{\mathtt{25}}}} = {\mathtt{160}}$$
Your answer is not correct MathGod1 :)
