You and your friend are selling tickets to a charity event. You sell 4 adult tickets and 11 student tickets for $148. Your friend sells 7 adult tickets and 5 student tickets for $145. What is the cost of a student ticket?
@ vera .... Just blurting out an answer serves absolutely no purpose!
4a + 11s = 148
7a + 5s = 145
solve the 2 equations in 2 unknowns
I suggest multiplying the first by 7 and the 2nd by 5 and then subtracting them
Apparently Vera in Pleasanton wants everyone to know about her ignorance.
