00:13
From the sale of $1 ,800 tickets.
00:24
The promoter charges $1 .20 for some tickets and $1 .30 for others.
00:35
Let x represent the number of $20 tickets and y represent the number of $30 tickets.
00:49
In part a, we are asked to find the equation that satisfy the sum of the tickets sold is $1 ,800.
00:59
Here, the total number of $20 tickets are x and the total number of $30 tickets are y, which is equals to 1 ,800.
01:12
So this represents the sum of the tickets sold is 1 ,800.
01:16
So this is the final answer for part a.
01:24
In part b, we are asked to find how much money is received from the sale of $20 tickets.
01:33
As x represent the number of $20 .00.
01:47
Tickets tickets so from here we can say that total money total money received from the sale of a sale of $20 tickets is 20 times x so this is the final answer part b in part c we are asked to find how much money is received from the sale of $30 tickets lit by representing the number of $30 tickets.
02:52
From here we can say that the total money received from the sale of the sale of $30 of $30 tickets is $30...
