Step-by-step explanation:
If J can paint a room in 3 hours, in 1 hour she gets
of the job done.
If A can paint a room in 4 hours, in 1 hour she gets
of the job done. We need to find out how long it takes them if they paint together. The equation for this is:
where x is the number of hours it takes them to get the job done together. Multiply everything through by 12x to get
4x + 3x = 12 so
7x = 12 and
x = 1.7 hours to get the room painted together.

Step-by-step explanation:
let a = the number of adult tickets
let c = the number of children tickets

we proceed by Substitution:
c = 12 - a
14.5a + 9c = 135.5
After some calculations we find
a=5 and c=7
