Question

Before a baseball game, a hot dog stand sold 9 hot dogs. During the game, the stand sold some hot dogs. The hot dog stand sold a total of 58 hot dogs before the game and during the game. How many hot dogs were sold during the game?

Answer 1

x = 3 dollars per burger

Step-by-step explanation: Call the prices of hamburger and hot dogs, x and y. Then we can write

3x + 2y = 13 and

2x + 5y = 16

Multiply the top by two and the bottom one by three and subtract...we get

6x + 4y = 26

-(6x + 15y = 48)
