Please show me how to solve the following problem: The ocncession stand is selling hot dogs and hamburger during the game. At half-time,they sold a total of 78 hamburgers and hot dogs and brought in $105.50. How many of each item did they sell if hamburgers sold at $1.50 and hot dogs sold at $1.25?

  • Math -

    # of burgers --- x
    #of hotdogs ---- 78-x

    1.5x + 1.25(78-x) = 105.50
    times 4
    6x + 5(78-x) = 422
    6x + 390 - 5x = 422
    x = 32

    32 hamburgers and 46 hotdogs
