Answer:

The amount of discount would be #$27#.

Explanation:

We know that the jacket's full price is #$90#.

If we take #$90# and multiply it by #0.70# (we get #0.70# by dividing #70/100#), this will give us our full price of the jacket after the discount, which is #$63#.

Now, if we take that #70# and subtract #100-70# we will get #30#. Divide #30/100# we get #0.30#.

Multiply #$90# by #0.30# and we will get the amount of our discount, #$27#.

You can check your answer by adding #63+27#, which should add up to our original price. In this case, #$90#.
