4. You and a friend go to the movies and split the cost of the movie tickets and snacks. You pay the bill. You tell your friend he owes only $9 because you owed him $4 from the last time you went to the movies. How much was the total bill? Let b represent the total bill. Identify the correct equation to represent this problem and the correct solution. (1 point)
A. B/2+ 4 = 9; b = $10
B. B/2– 4 = 9; b = $26
C.B/2+ 9 = 4; b = $26
D.2b – 4 = 9; b = $7.50
(WILL GIVE MEDAL
The answer is B: B/2 - 4 = 9 You are taking half of the total bill (what the friend owes), then subtracting the 4 dollars that he does not have to pay because you owe him. This gives you the total of $9. So, the total cost is $26.
