A m + 0.51m + 0.51
B m + 1.51m + 1.51
C m + 1.63m + 1.63
D m + 1.75m + 1.75
E m + 2.83
The correct expression is m + 1.51. This is because the price first increases by m dollars, making the price 1.63 + m dollars per dozen. Then the price decreases by $0.12 per dozen, making the final price 1.63 + m - 0.12 = m + 1.51 dollars per dozen. Therefore the answer choice is not in the options, none of the response is correct.
