C+A=708
1.75C+2A=1326.25
multiply first one by -2
-2C-2A=-1416
1.75C+2A=1326.25
-0.25C=-89.75
C=359 children@1.75=628.25
A=349 adults @2=698
Total is $1326.25

Let n be the number of adults that day. Then:
2n+1.75(708-n)=1326.25
200n+175(708-n)=132625
200n+123900-175n=132625
25n=8725
n=349
There were 349 adults, and 359 children that day ☺☺☺
