Answer:$378.95

Step-by-step 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

Original height = original width = x mm

1. She made an enlarged copy...
height = 2x
width = 2x

2. She cut off a rectangle...
height = 2x
width = \frac{2}{3} *2x= \frac{4}{3}x

3.She doubled the width...
height = 2x
width = 2*\frac{4}{3}x = \frac{8}{3}x

height * width = area

2x * \frac{8}{3}x=139 \ 968  \\ \\ \frac{16}{3}x^2= 139 \ 968 \\\\ x^2=139 \ 968: \frac{16}{3}=139 \ 968 * \frac{3}{16}=  8 \ 748*3 = 26 \ 244 \\  \\ x= \sqrt{26 \ 244} = 162 \ mm

Original height was 162 mm
