A school play sold 350 tickets in total, consisting of adult tickets and student tickets. Adult tickets were priced at $12.50 each, and student tickets were priced at $7.00 each. If the total revenue from ticket sales was $3,185, which system of equations represents the number of adult tickets sold, $a$ , and the number of student tickets sold, $s$ ?

A.

$a + s = 350 12.50 a + 7.00 s = 3185$

B.

$a + s = 3185 12.50 a + 7.00 s = 350$

C.

$a + s = 350 7.00 a + 12.50 s = 3185$

D.

$a + s = 3185 12.50 a + 7.00 s = 3185$
