anonymous · Answer

let adults=x
5x+1.50(1200-x)=3200
solve for x
or let adults=x
and students=y
x+y=1200
5x+1.50 y=3200
find x and y

anonymous · Answer

for your options use second method

anonymous · Answer

for elimination
5x+5y=6000 
subtract and find y
and then find x
for substitution y=1200-x
5x+1.50(1200-x)=3200
find x and then y
