Problema Solution
Maggie has a job working in an office for $10 an hour and another job driving a tractor for $12 an hour. One week she works in the office twice as long as she drives the tractor. Her total income for that week is $416. How many hours did she spend at each job?
Answer provided by our tutors
let
x = the hours she worked in the office
y = the hours she drove a tractor
One week she works in the office twice as long as she drives a tractor
x = 2y
Her total income for that week is $416
10x + 12y = 416
by solving the system of equations
x = 2y
10x + 12y = 416
we find
x = 26 hr
y = 13 hr
