#### Amount Saved? Any 2 or More

The following offer was made in a store ad. "Any 2 or More – 14.99 Regular $20.00"

1. How much do I save?

2. If the store rewrites the ad as a "percent off" ad,how would the ad read?

1.The first question addresses what we want to know as shoppers or consumers.

Well, remember two items must be purchased in order to save. In order to make the calculation easier, let us round $14.99 to the nearest cent. Why? The intent of rounding is to have a number close to the original number but easier to work during calculations.

Round $14.99 ---$15.00

If the items are purchased separately, the total is $20 +$20 = $40

If two items are purchased at the same time, the cost is $15 + $15 = $30

Savings ---- Subtract sales total from the original total.

$40 - $30 =

Let's plug the above numbers into a percent proportion.

Part/whole = % / 100

Part = amount saved; whole = total when purchased separately; percent = unknown

10 / 40 = X / 100

Cross multiply and set up an equation to solve

40X = 1000

Divide both sides by 40

X = 25

Thus, 25% was saved. The ad could possibly read, "Save 25% when you buy 2 or more."

Percent * Whole = Part

40X = 10

Divide both sides by 40

X = .25

Change to percent by moving the decimal two places to the right. This is the same as multiplying by 100.

Thus, 25% was saved. The ad could possibly read, "Save 25% when you buy 2 or more."

**We can ask two questions.**1. How much do I save?

**An alternative method - use the Percent Equation**Percent * Whole = Part

40X = 10

Divide both sides by 40

X = .25

Change to percent by moving the decimal two places to the right. This is the same as multiplying by 100.
