3. A train set costs $120.00. Find the discount if it is on sale for<br> 30% off.
Leno4ka [110]

Answer:

36

Step-by-step explanation:

To find the discount, you will need to find 30% of $120, so you will need to do:

120*0.3=36

Also, if you were asking for the COST if it was 30% off, it would be 84 as 120-36=84.

(I hope this helps!)
