Which is the best option?

In order to find the best option we want to find the cost per oz of each price:

1 oz COST: $1.69 DISCOUNT: Buy one get one free

If he buys a pair number of it, let's say he buys 2 oz.

Then the price for 2 oz will be $1.69

Then, the price per oz will be

$1.69/2 = $0.845

9 oz COST:$2.78 DISCOUNT: Coupon for $5.00 off when buying 4 or more

Let's say he buys 4 bags , then it would normally cost

4 x $2.78 = $11.12

With the discount it would cost

$11.12 - $5 = $6.12

If he buys 4 bags then he would buy 9 x 4 = 36 oz

Since

$6.12/36 = $0.17

The maximum cost for each oz is:

$0.17

15.25 oz COST: $3.98 DISCOUNT: 20% off

If a 15.25 bag has a 20% discount, then it cost is the 80% of $3.98.

We find any percentage by dividing it by 100 and then multiplying the result by the number: in this case

80/100 = 0.8

then 80% of $3.98 is given by

0.8 x $3.98 = $3.184

We divide it by 15.25 in order to find the price per oz:

$3.184/15.25 = $0.21

28 oz COST: $4.98 DISCOUNT: No coupon offered

We find the cost per oz by dividing $4.98 into the total number of ounces:

$4.98/28 = $0.18
