You can put this solution on YOUR website! let x = total income.
20% of that was spend for materials.
that means that 80% of that was spent for other purposes.
that means that:
.80*x = 78000
divided both sides of this equation by .8 to get:
x = 78000 / .8 = 97500
total income equals x which is equal to 97500
20% of that is spend for materials which makes expenditures for materials equal to .20 * 97500 = 19500.
80% of that is spent for other purposes which make expenditures for other purposes equal to .80 * 97500 = 78000
add the 2 pieces together to get 19500 + 78000 = 97500 which equals the total expenditure.
