A Sale at Tinley’s Department Store Tinley’s department store is having a 25% off sale. Victor has a $15 Tinley’s gift certificate that he wants to use towards a sweater with an original price of $32.00. He is unsure which method the sales clerk will use to calculate the amount owed. Method #1: Subtract $15 from the price and take 25% off the resulting price. Method #2: Take 25% off the original price and then subtract $15.

Method 1: $12.75

Method 2: $9

Step-by-step explanation:

method #1: 32-15 is $17

In order to take off a percentage, we must find that percentage of the amount. To do this, we must multiply by the percent in decimal form, so

Now, this amount just represents the percent of 17 we would take off, so we must take that amount off.

We would pay $12.75

Method #2:

There are a few ways to do this with 25%. we know 25% is 1/4, and 1/4 or $32 is 8. so we can simply take that off from the start. Otherwise, we can follow the method above as follows

Again, this is the amount off so we must subtract.

now, we subtract 15.

We would pay $9 using this method.

Hope this helps!
