Answer:

There would only be 3 oz of the box left.

Step-by-step explanation:

In order to find this, subtract the two amounts eaten from 1 whole box.

1 - 3/10 - 3/5. = Leftover

Now give them all common denominators and perform the indicated operations.

10/10 - 3/10 - 6/10 = Leftover

1/10 = Leftover.

Now that we have the percentage left, we multiply it by the amount in the whole box.

1/10 * 30 = 3oz
