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.
b÷ 2 4 – b = $10
b÷2 4 = 9; b = $ 26
b ÷ 2 + 9 = 4; b = $ 26
2b – 4 = 9; b = $ 7.50
danielle went ice skating. it cost $3 an hour and $5 for skate rental. if danielle spent $11, how many hours did she ice-skate? let h represent the number of hours spent ice-skating. identify the correct equation to represent this problem and the correct solution.
3h – 5 5 = 11; h = 2
5h + 3 = 11; h = 1.6
3h + 5 = 11; h = 2
5h – 3 = 11 ; h = 2.8
