On a monthly basis, Esperanza pays $600 in rent, 3/5 as much money on food as she pays on rent and her mortgage bill costs three times the amount of money she spends on food. If she saves $2000 and also pays the equivalent of 2/5 of her savings in taxes, calculate her gross monthly salary. Let's be accurate as possible.
Esperanza pays 3 / 5 * $600 = $360 on food. She also spends 3 * $360 = $1080 on mortgage bills. Her expenses in taxes amount to 2 / 5 * $2000 = $800. Esperanza's total monthly expenses are $800 on taxes + $1080 on mortgage bills + $360 on food + $600 on rent = $2840. Her gross salary is $2840 for expenses + $2000 on savings = $4840.
The answer: 4840.
