If 1 bucket + 5 jars = 1 tub, and 3 buckets + 2 jars = 2 tubs, how many jars are equal to 1 tub?

There are 13 jars in 1 tub.

Step-by-step explanation:

1 bucket + 5 jars = 1 tub

3 buckets + 2 jars = 2 tubs

Let buckets be = b

Let jars be = j

Let tubs be = t

So, we have :

We get

We have to find the relation between j and t.

So, deducing equations in terms of j and t;

Substituting b here

This means that 13 jars equals to 1 tub, or we can also say that, there are 13 jars in 1 tub.

(a) the volume of the cone is 20/3 in3

hence, option a is correct.
