    Answer:

    $19,500

    Step-by-step explanation:

    In this question, the first thing we do

    Is to calculate the amount of gold that was used in making 7,800 smartphones. We proceed as follows:

    Firstly, 10 ounces made 5,200 smartphones, then x ounces will make 7,800 smartphones

    Thus 10 * 7,800 = 5,200 * x

    x = 78,000/5200 = 15 ounces

    This means that 7,800 smartphones were made using 15 ounces of gold

    Now, we know that the value of an ounce is $1,300. Thus, the value of 15 ounces would be 15 * 1,300 = $19,500
