Final answer:
Mrs. Money had salary is $1350.
Step-by-step explanation:
To find out what fraction of her salary Mrs. Money had left, we need to calculate the portion of her salary that she spent on food and transport.
Let's assume her salary is represented by the variable S.
She spent S/3 on food and (2/3)(S/3) = 2S/9 on transport.
The remainder is (S - S/3 - 2S/9) = 4S/9.
We can set up an equation to find the value of S by equating the fraction of her salary left to the given amount of $600: (4S/9) = 600.
Solving this equation, we find that her salary, S, is $1350.
