Question

A empty bowl has a mass of 600 grams. Sue puts 8 cans of equal mass into bowl. She weighs the filled bowl. It has a mass of 7 kilograms. What is the mass of each can in grams?

Answer 1

Option B (800))

Explanation:

We know that the mass of the empty container is 600 gr

And when they put 8 cans of equal mass then the final weight of the container is 7 kilograms or 7000 grams

If we call x the weight of the cans then this situation can be represented.

Now we solve the equation for the variable x.

Answer 2

6400/8 = 800gm

because 7000-600= 6400

and 6400/8 is our answer = 800grams

Explanation:

1) First we can convert kg into grams

2) Then we deduct 600grams from the mass to show the weight of the mass without the weight of the bowl = - 600grams

1) 7kg = 7000gm

2) 7000-600 = 6400

6400/8 = 800 grams
