- 20 bolsas de \(\frac{3}{2}\) kilo cada una.

Calcula el número de kilos de café que le quedan todavía por envasar.

Answer :

Final answer:

The merchant has already packaged 71 kilos of coffee from 120 kilos. Therefore, he still has 49 kilos of coffee left to package.

Explanation:

A merchant has 120 kilos of coffee. He has already packaged 40 bags of 1/2 kilo each, 28 bags of 3/4 kilo each, and 20 bags of 3/2 kilo each.

To calculate how many kilos of coffee he still has to package, first, we need to determine how much coffee he has already packaged. This can be done by multiplying the number of bags by the weight of each bag and summing the results. So, the merchant has packaged:

  • 40 * 1/2 = 20 kilos in the first set of bags,
  • 28 * 3/4 = 21 kilos in the second set of bags,
  • 20 * 3/2 = 30 kilos in the third set of bags.

This means the merchant has packaged a total of 20 + 21 + 30 = 71 kilos of coffee. Therefore, of the original 120 kilos of coffee, he still has 120 - 71 = 49 kilos of coffee left to package.
