    The total number of trucks sold=13

    The total number of dolls sold=52

    Step-by-step explanation:

    Step 1: Determine price per unit of each toy type

    Price per doll=$24

    Price per truck=$17

    Step 2: Derive an expression for the total cost of trucks and dolls sold

    Total cost = (Price per doll*number of dolls sold) + (price per truck*number of trucks sold)

    where;

    Price per doll=$24

    Number of dolls sold=d, but 4 times as many dolls than trucks were sold, d=4*t=4 t

    Price per truck=$17

    Number of trucks sold=t

    Total cost=$1469

    replacing;

    1469 = (24*4 t) + (17*t)

    96 t+17 t=1469

    113 t=1469

    t=1469/113

    t=13

    d=4 t=4*13=52

    The total number of trucks sold=t=13

    The total number of dolls sold=d=52
