A11 1 * [ (2*5) - (5*2)] = 0
a12 = -4 *(5*5) - 2*1) = 23*-4 = -92
a13 = 4 * (5*5) - (1*2) = 23 * 4 = 92
a21 = 0
a22 = 2 * (5-4) = 2
a23 = -2 * (5-4) - -2
a31 = 0
a32 = -5*(2-20) = 90
a33 = 5 * (2-10) = -90
Adding these gives zero
Answer is B:- 0
The answer is the unit price for each ounce would be 0.25 (of course rounded to the nearest cent) just divide 3.99 by 16 then round to the nearest thousandths
