Answer:
$18.90
Step-by-step explanation:
The way to do percentages is actually pretty easy.
since it's taking 30% of you are left with 70%. Take 70 and divide it by 100. This gives you .70
Now what you do is you take the price of the time and multiply it by the .70
So 27.00 * .7 = 18.90
So Noah paid 18.90
