Given that the total budget is $200, the sum of the individual amounts budgeted for the various kinds of bill must be equal to $200. If 1/5 is for phone bill and 65% is for food then,
Budget for;
Phone bill = 1/5 * $200
= $40
Food = 65% * $200
= $130
Since the rest is for New cloths, the amount for new cloths will be the difference between the total budget and the amount spent on other expenses.
