Question 1128474
lower : x
upper : y
x + y = 587 subtract y from both sides and you get x = 587 - y We'll use this value for x next.
12.50x + 8.00y = 6,046.00
Now substitute for x:
12.50(587 - y) + 8.00y = 6,046.00
7,337.50 - 12.50y + 8.00y = 6,046.00
-4.50y = -1291.50 divide to find y, and remember -/- = +
y = 287
287 of the $8 tickets were purchased, and 587-287 = 300 of the 12.50 tickets were purchased
