Question

Tickets for the monster truck rally cost $12 for children and $20 for adults. Last

night 400 total tickets were sold for a total of $6000. Use c for the child tickets and
a for adult tickets. If one of the equations for this system is a + c = 400, write
the second equation for this system below.

Answer 1

20a + 12c = 6000

Explanation:

a = adult tickets

c = child tickets

$20 for adults, $12 for children, for a total of $6000

20a + 12c = 6000

a + c = 400
