    Answer: the equation is 4t = 3.60

    The cost of 1 pound of banana is $0.9

    Step-by-step explanation:

    Let t represent the cost of 1 pound of banana in dollars.

    Gavin paid for 4 pounds of bananas. This means that the total cost of 4 pounds of banana will be 4 * t = $4t

    He gave a $10 bill to the seller and he was given back $6.40. This means that the actual cost of 4 pounds of banana would be

    10 - 6.40 = $3.60

    Therefore,

    4t = 3.60

    t = 3.60/4 = $0.9
