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 $11,000. What is her income?
Answer provided by our tutors
let 'x' be her income then
1/3 of her annual income for board: x/3
1/12 for clothes: x/2
1/3 for other expenses: x/3
if we sum up all the spending + the savings we will have her income that is
x/3 + x/12 + x/3 + 11000 = x
by solving the equation we find
x = $44,000
her income is $44,000.
