Respuesta :
a + s = 480......s = 480 - a
8a + 5s = 2892
8a + 5(480 - a) = 2892
8a + 2400 - 5a = 2892
8a - 5a = 2892 - 2400
3a = 492
a = 492/3
a = 164 <=== there were 164 adult tickets sold
8a + 5s = 2892
8a + 5(480 - a) = 2892
8a + 2400 - 5a = 2892
8a - 5a = 2892 - 2400
3a = 492
a = 492/3
a = 164 <=== there were 164 adult tickets sold
Answer : The number of adult tickets sold was, 164 tickets.
Step-by-step explanation :
Let the number of adult tickets be, x
So, the number of student tickets will be, (480-x)
Total cost of tickets = $2892
Cost of 1 adult ticket = $8
Cost of 1 student ticket = $5
Thus, the equation will be:
[tex]8x+5(480-x)=2892[/tex]
By solving the term, we get the value of 'x'.
[tex]8x+2400-5x=2892[/tex]
[tex]8x-5x=2892-2400[/tex]
[tex]3x=492[/tex]
[tex]x=164[/tex]
Number of adult tickets = x = 164
Number of students tickets = (480-x) = (480-164) = 316
Thus, the number of adult tickets sold was, 164 tickets.
