If 4.8 kg of pecans were used, that means that of the total nuttly chocalate bars (in kg) made that day, 22.0% of it is equal to 4.8 kg.
Mathematically that means,
22.0% x chocalate bars = 4.8
0.22 x chocolate bars = 4.8
Working backwards,
we have chocolate bars = 4.8/0.22 = 21.82 kg
Hence, the weight of the chocolate bars amade is equal to 21.82 kg. Since we need the weight in pounds, we must take note that 1 kg = 2.2 lbs. So, we have
21.82 kg = 21.82(2.2) = 48.00 pounds
Answer: 48.00 pounds
