Answer:
14.25
Step-by-step explanation:
So, lets go over our information.
We have a price of 15 dollars.
And it is 5% cheaper.
This means that the price is 95% of what it used to be.
We must find 95% of 15.
We know that to put 95% into decimal form, we must divide by 100:
95/100
=
0.95
So we know we must multiply 15 by 0.95:
15x0.95
=
14.25
So our price is now 14.25 dollars
hope this helps! :)
