Ricci saved $200 from her salary and spent the rest. She spent 1/9 of the expenditure on a blouse, $40 on a scarf and the rest on books. The amount spent on the scarf was $20 less than that spent on the blouse. What was her salary?
Solution
1/9 of expenditure (blouse) ----- $20 + $40 (scarf) = $60
9/9 of expenditure ----- 9 x $60 = $540
Salary ----- $540 + $200 (saved) = $740
Answer: Her salary was $740.
