David is running a concession stand at a soccer game. He sells nachos and sodas. Nachos cost $1.50 each and sodas cost $0.50 each. At the end of the game, David made a total of $78.50 and sold a total of 87 nachos and sodas combined. Which system of equations represents this situation?
$1.50N + $0.50S = $78.50
N + S = 87
$1.50N + $0.50S = $78.50
$1.50N + $0.50S = 87
N + S = $78.50
$1.50N + $0.50S = 87
N + S = $78.50
N + S = 87
On Monday Joe bought 10 cups of coffee and 5 doughnuts for his office. It cost $16.50. On Tuesday he bought 5 cups of coffee and 10 doughnuts for a total of $14.25. Which system of equations models this scenario?
10c + 5d = $14.25
5c + 10d = $16.50
10c + 5d = $16.50
5c + 10d = $14.25
c + d = 10
5c + 10d = $16.50
c + d = 5
5c + 10d = $16.50
