The pie graph shows Katie and David's household budget. The 25% mark represents utilities. If Katie and David spend $400 a month on utilities, what is the total monthly budget?

A) $1200

B) $1600

C) $2000

D) $2500

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
