if total ticket sales were $1625 adult tickets were $7.00 and student tickets were $3.00 and twice as many students bought tickets than adults, how many students and adult tickets were sold?

Answer 1

7 a + 3 s = 1625

s = 2 a

so
7 a + 3 (2 a) = 1625

7 a + 6 a = 1625

13 a = 1625

a = 125
so s = 250
