Question 1156418

James' school is selling tickets to the annual talent show. On the first day of ticket sales, the school sold 6 adult tickets and 7 child tickets for a total of $155. The school took in $258 on the second day by selling 8 adult tickets and 14 child tickets. What is the price each of one adult ticket and one child ticket? 
<pre>Let cost of each adult's ticket be A, and each child's child's, C
We then get: 6A + 7C = 155 ------ eq (i)
Also, 8A + 14C = 258____2(4A + 7C) = 2(129)_____4A + 7C = 129 ------- eq (ii)
2A = 26 ------ Subtracting eq (ii) from eq (i)
A, or {{{highlight_green(matrix(1,9, Cost, of, each, "adult's", ticket, "=", 26/2, "=", "$13"))}}}
You should now be able to find the cost of a child's ticket!
