X = car cost
y = appliances cost
x + y = 15200
7.5%(y) + 6.5%(x) = 1015
x=12500
y= 2700
So the car costs $12,500

Shakila paid $130.80 in total.
Explanation: 120*1.09=130.80
Find the ticket unit cost: divide the total paid, $324, by the number of tickets, x. Then the form of the unit cost is
$324
--------- .
x
This question is highly unusual in that you write "x" as the number of tickets sold, instead of a specific number of tickets. Supposing that you'd sold 100 tickets for $324, then the unit cost would be, much more typically, a numeric ratio:
$324
----------------- = $3.24/ticket
100 tickets
