Answer:$378.95

Explanation:

Change it all to fractions.

3/10 of her salary on rent

2/5 of her salary on entertainment

1/4 of her salary on living expenses.

Add them

3/10 + 2/5 + 1/4 = 6/20 + 8/20 + 5/20 = 19/20*S

(19/20)*S = 7200

S = 7200*20/19

------

She saved the remaining 1/20 of S = 7200/19

saved =~ $378.95
