Best ResponseYou've already chosen the best response.0let x = number of students, y = number of adults ; set up two equations using the information you have, that is: 8x+10y = 518 and x+y = 63 , now solve for x or y and plug in

Best ResponseYou've already chosen the best response.0The above poster is right in using a system of equations, but I will show you how to do it with a single variable. Let x be the number of adults and 63x be the number of students, since those who are not adults must be students. So, 10x+8(63x)=518. Simplify this to 10x+5048x=518, simplify to 2x=14, x=7so 7 adults went and 56 students went :).
