Question 1202396: There are 120 people who attend a concert. Each adult ticket costs $3.50.
Each child ticket costs $2.00. If the total revenue for the ticket sales was
$324.00, state how many adult tickets and how many children tickets were
sold. Found 2 solutions by mananth, josgarithmetic:Answer by mananth(16946) (Show Source):
3.50 x + 2.00 y = 324.00
Eliminate y
multiply (1)by 2
Multiply (2) by -1
2.00 x 2.00 y = 240.00
-3.50 x -2.00 y = -324.00
Add the two equations
-1.50 x = -84.00
/ -1.50
x = 56
plug value of x in (1)
1.00 x + 1.00 y = 120
56.00 + 1.00 y = 120
1.00 y = 64.00
y = 64
Ans x = 56
y = 64
56 Number of adult tickets sold
64 Number of child tickets sold
