Answer: 565 general admission and 430 lower-level seating tickets sold (Answer (D))
Steps:
Let x be the number of general admission tickets, and y be the number of lower level tickets.
Set up the two equations:
68762.5 = x * 47.50 + y * 97.50 (total price as a sum of individual volumes)
x + y = 995 (sum of individual count = total count of tickets sold)
solve for x, y:
x = 995 - y
plug into the first equation:
68762.5 = (995-y) * 47.50 + y * 97.50
solve for y:
y = 430
then x = 565
x = 565 and y = 430
I think its D because don’t functions only have 1 equation?
145 cause 40+85+90 equals 215 n then subtract that from 360
AB + CD = BC + DA
<span>Where A, B, C, and D are points on the quad, and AB is the length of the line A to B, etc. </span>
<span>Since you know three sides, you can easily solve for the fourth. </span>
