Answer provided by our tutors
let
t1 = the money Brian earns tutoring
g = the money Brian earns pumping gas
t2 = the money Brian's sister earns tutoring
Brian earns twice as much each week as a tutor than he does pumping gas
t1 = 2g
his total weekly wages are $150 more than that of his younger sister
t1 + g = 150 + t2
she earns one quarter as much as Brian does as a tutor
t2 = (1/4)t1
by solving the system of equations
t1 = 2g
t1 + g = 150 + t2
t2 = (1/4)t1
we find
t1 = $120
