    Answer: apples = 7 and bananas = 8

    Step-by-step explanation:

    Let x represent the number of apples and y represent the number of banana,

    and it was said that the total apples and bananas altogether is 15, that is

    x + y = 15 ... equation 1

    Also,

    1.25x + 0.40y = 11.95 ... equation 2

    Solving the two equations simultaneously,

    From the first equation, x = 15 - y ... equation 3

    substitute equation 3 into equation 2, we have

    1.25 (15 - y) + 0.40y = 11.95

    18.75 - 1.25y + 0.40y = 11.95

    18.75 - 0.85y = 11.95

    18.75 - 11.95 = 0.85y

    6.8 = 0.85y

    therefore y = 6.8/0.85

    = 8

    substitute y = 8, into equation 3

    x = 15 - 8

    x = 7

    Therefore, she bought 7 apples and 8 banana
