    C 36 Correct Answer Incorrect Answer
    D 40 Correct Answer Incorrect Answer

    Solution

    Let the price of one apple be x, and the price of one banana be y. 3x+2y=46        (Equation 1) 5x+4y=82        (Equation 2)   Eliminate one variable Multiply Equation (1) by 2   6x+4y=92        (Equation 3) Now subtract Equation (2) from Equation (3)-   (6x+4y) -(5x+4y) = 92-82 x = 10 Substitute x = 10 back into Equation (1) 3(10) + 2y = 46   30 + 2y = 46 2y = 16 y = 8 Calculate the price of 2 apples and 3 bananas =2x + 3y = 2(10) + 3(8) = 20 + 24 = 44 So, the total price of 2 apples and 3 bananas is 44.
