5. Don Carlos, un gran panadero, está preparando unos deliciosos panes de queso y ha comprado 12 libras de queso; para completar sus ingredientes debe comprar una cantidad de harina que corresponda al doble de la cantidad de queso. La cantidad de harina que debe comprar don Carlos es:

He needs 24 lb of flour

El necesita 24 libras de harina.

Explanation:

Ok, this can be translated to:

"Don Carlos, a great baker, is making some delicious cheese bread and has bought 12 pounds of cheese; To complete your ingredients you must buy an amount of flour that corresponds to twice the amount of cheese. The amount of flour Don Carlos must buy is:"

Then, if the amount of cheese is 12 lb, and we the double of that, we need:

2*12lb = 24 lb

He needs 24 lb of flour

Necesita 24 libras de harina.
