Question 1126631
5a + 1c = 31.80 multiply all times 5
2a + 5c = 23.30 multiply all times -1 and add
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
25a + 5c = 159
+
-2a +-5c = -23.30
----------------
23a + 0c = 135.70
23a = 135.7
a = 5.90 adult tickets cost 5.90 each
To find the cost of children's tickets I'll use the first equation:
5a + 1c = 31.80
5(5.90) + 1c = 31.80
29.50 + c = 31.80
c = 2.30
Use the 2nd equation to check this answer:
2a + 5c = 23.30
2(5.90) + 5(2.30) = 
11.80 + 11.50 = 23.30 Correct
