Question

for a Saturday matinee, adult tickets cost $5.50 and kids under 12 pay only $4.00. If 70 tickets are sold for a total of $355, how many of the tickets were adult tickets and how many were sold to kids under 12?

Answer 1

Let x be tickets for adults
Y be tickets for kids under 12, then
5.5x + 4 y = 355 ,
x+y = 70=>(y = 70-x)
5.5x + 280-4x=355
1.5x=75
X=50
Y=20
