Total amount(in kilogram) of sugar purchased by Michael = 515 kg
Another amount(in kilogram) of sugar purchased by Michael= 312 kg
Total amount of sugar purchased by Michael
= 515 kg + 312 kg
= 827 kg
Now, we have to find the total amount of sugar purchased by Michael in pounds.
Since 1 kilogram = 2.2 pounds
Therefore, total amount of sugar purchased in pounds= [tex] 827 \times 2.2 [/tex] pounds
= 1819.4 pounds
So, Michael purchased 1819.4 pounds of sugar.
