If a toy that costs $2.99 is at a 30% discount then you first need to make 30% a decimal.
30% = .3
Now multiply $2.99 by .3 to find the discount which is .897
Since .897 has a thousandths place we need to round that which would make it 90 cents.
Now we know there is a 90 cent discount on a $2.99 toy.
take $2.99 - 90 cents = $2.09
The toy costs $2.09 after a 30% discount
