They mowed total of 11/15 (5/15 + 2/5) already, so they still have 4/15.
Answer
I think that there's 5 but i'm probably wrong so I wouldn't use my answer if I were you
A+c=100
3a+2c=275, from the first c=100-a making the 2nd equation become:
3a+2(100-a)=275 perform indicated multiplication on left side
3a+200-2a=275 combine like terms on left side
a+200=275, subtract 200 from both sides
a=75, and since c=100-a
c=100=75=25
So the answer is D. 25 children and 75 adults
Equation 1: a+c=100
Equation 2: 3a+2c=275
