A has 3 jars and B has 1 jar, each jar filled with 2.2 g of candies.

What is the total amount of candies in all the jars?

The correct option is A 8.80 g
A has 3 jars and B has 1 jar

So, total amount of jars
= 3 + 1
= 4

Each of the jar contains 2.2 g of candies each.

∴ The amount of candies filled in 4 jars = (4 $\times$ 2.2) g

Multiplying 4 with 2.2 by standard method, we get:

So, there are, in total, 8.8 g of candies in all the jars.
