0.5x + 0.33x + 0.1x + 15 = x
0.93x + 15 = x
15 = 0.07x
15/0.07 = x

M= Anne's money
1/2M + 1/3M + 1/10M + 15 = M................multiply by the LCD 30
30*1/2M + 30*1/3M + 30*1/10M + 30* 15 = 30*M
15M + 10M + 3M +450 = 30M
28M + 450 = 30M
450 = 2M
M = $225 to start
1/2M + 1/3M + 1/10M + 15 = M................multiply by the LCD 30
30*1/2M + 30*1/3M + 30*1/10M + 30* 15 = 30*M
15M + 10M + 3M +450 = 30M
28M + 450 = 30M
450 = 2M
M = $225 to start
