    Answer:

    Weight of dried bananas = 34.75 kg

    Weight of dried apricot = 15.25 kg

    Step-by-step explanation:

    Given that:

    Cost of dried bananas = $4.59 per kg

    Cost of dried apricots = $6.59 per kg

    Total weight of mixture = 50 kg

    Sales price of dried fruit = $5.20 per kg

    To find:

    The weight of each type of dry fruit = ?

    Solution:

    Let weight of dried bananas = x kg

    Let weight of dried apricot = y kg

    x+y=50 ...... (1)

    Total cost of dried bananas = Cost of dried bananas per kg multiplied by weight of dried bananas

    Total cost of dried bananas = $4.59x

    Total cost of dried apricots = Cost of dried apricots per kg multiplied by weight of dried apricots

    Total cost of dried apricots = $6.59y

    As per question statement,

    Total cost of dry fruits = $5.20 \times 50 = $260

    260 = 4.59x+6.59y......(2)

    Using substitution:

    By equation (1):

    x = 50-y

    Putting in equation (2):

    260 = 4.59 (50-y)+6.59y\\\Rightarrow 2y = 260 - 229.5\\\Rightarrow y = 15.25\ kg

    x = 50 - 15.25\\\Rightarrow x = 34.75\ kg

    Therefore, the answer is:

    Weight of dried bananas = 34.75 kg

    Weight of dried apricot = 15.25 kg
