got a question that has stumped me
In order to attract the Olympic Games to Sydney the NSW Government spent $600 000 on TV, radio and magazine advertising. As much was spent on TV advertising as on radio and magazines together and the amount spent on magazines and TV combined was equal to 3 times that on radio. Let t, r and m represent the amounts spent on television, radio and magazine advertising respectively.
Express the information on advertising as a system of linear equations and solve for t, r and m.
best ive got is
t+r+m=600000
t= r+m
and
r= m+t/3
