Question

At a store the money obtained for 70 empty bottles can buy 35 pencils.Hiw many bottles would the money from 90 bottles buy

Answer 1

The question contains a mistake in a formulation. There should be "pencils" instead of "bottles": “How many pencils would the money from 90 bottles buy?” instead of "How many bottles would the money from 90 bottles buy?"

x/90=35/70;

x=35*90/70;

x=45.

Answer: 45 pencils would buy the money from 90 bottles.
