    Hi jjjinapinch,

    We're told that all donuts are priced equally and all bagels are priced equally (meaning that all donuts cost the same price and all bagels cost the same price). We're asked for the total price of 5 donuts and 3 bagels. In simple terms, we're asked for the value of 5D + 3B....

    1) At the bakery, the total price of 10 donuts and 6 bagels is $12.90.

    With the information in Fact 1, we can create the following equation:
    10D + 6B = $12.90

    We can simplify this equation by dividing both sides by 2, which gives us...
    5D + 3B = $6.45
    We now have the exact answer to the question: $6.45
    Fact 1 is SUFFICIENT

    2) At the bakery, the price of a donut is $0.15 less than the price of a bagel.

    With the information in Fact 2, we can create the following equation:
    D = B - $0.15
    Unfortunately, the answer to the question will vary depending on the values of B and D...
    For example, the values....
    B = $1.00, D = $0.85
    B = $2.00, D = $1.85
    ...would lead to different answers to the given question
    Fact 2 is INSUFFICIENT

    Final Answer: A
