Problema Solution
Amy makes three times as much as an actuary as she does a writer. Her total income is $40000 more than her brother. Her brother earns half as much as Amy does as an actuary. What is Amy's salary as an actuary?
Answer provided by our tutors
let
a = Amy's salary as an actuary
b = her brother's salary
Her total income is $40000 more than her brother:
a = 40000 + b
Her brother earns half as much as Amy does as an actuary:
b = (1/2)a
by solving the system of equations:
a = 40000 + b
b = (1/2)a
we find:
a = $80,000
b = $40,000
