Problema Solution
A person spends 1/3 of her annual income for board, 1/12 for clothes, and 1/3 for other expenses, and saves $7,000. What is her income?
Answer provided by our tutors
let 'x' be the income
(1/3 for board) + (1/12 for clothes) + (1/3 for other expenses) + (the saved $7,000) = the total income
x/3 + x/12 + x/3 + 7000 = x
by solving the equation we find
x = $28,000
her income is $28,000.
