Answer is B. $1,600
Given:
part = $400
percentage of the part = 25%
whole = ?
To get the whole or total monthly budget, simply divide the part by its corresponding percentage.
$400 / 0.25 = $1600
Other formulas to consider if other facts are given:
% of Part to the Whole = Part/Whole * 100%
= 400/1600 * 100%
= 0.25 * 100%
= 25%
Value of the part of a whole = Whole * % of part
= 1600 * 25%/100%
= 400
