Answer: (A) 19.3%
<u>Step-by-step explanation:</u>

Vodka + Vermouth + Olive = Total Cost
$2.59 + $0.12 + $0.15 = $2.86

The equation can be (3450-1000)<span>÷7=350.</span>
the problem is a pattern that multiplies by two and subtracts one each time.
3x2=6 6-1=5 5x2=10 10-2=9 9x2=18 18-1=17 17x2=34 34-1=33
4x = student tickets, 7x = adult tickets
4(120) + 7x = 1500
480 + 7x = 1500
7x = 1020
X = 145 adult tickets
