Answer:
You would save $2.25.
Step-by-step explanation:
In order to find discount on an item, you need to multiply the discount by the original amount of the item. In this case, the cake you want regularly costs $9. If the sale includes a 25% discount, then you need to first convert your percentage to a decimal by dividing by 100:

You can then take this amount multiplied by the original cost of the cake to get your discount:
0.25 x 9 = 2.25, so you would save $2.25 with the discount and pay only $6.75 for the cake you want.
