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.
Esperanza pays 3/5* $600 = $<<3/5*600=360>>360 on food.
She also spends 3*$360 = $<<3*360=1080>>1080 on mortgage bills.
Her expenses in taxes amount to 2/5*$2000 = $<<2/5*2000=800>>800
Esperanza's total monthly expenses are $800 on taxes + $1080 on mortgage bills + $360 on food + $600 on rent = $<<800+1080+360+600=2840>>2840
Her gross salary is $2840 for expenses + $2000 on savings = $<<2840+2000=4840>>4840
