The answer is: Number of adult tickets: 20. Number kid's tickets: 50.
Step-by-step explanation:
5.50a + 4.00k = 310
a + k = 70
a = 70 - k
5.50(70-k) + 4.00k = 3.10
385 - 5.5k + 4k = 310
-1.5k = 310 - 385
-1.5k = -75
k = -75 / -1.5 = 50
Find the number of adult tickets:
a + 50 = 70
a = 20
Proof:
5.50(20) + 4.00(50) = 3.10
110 + 200 = $310
