Steri-strips cost $4.95 per box, there are 100 per box. If an orthopedic surgical group uses 200 Steri-strips a month, how much would be saved in a year by making a single purchase for a year's supply rather that 12 monthly purchases.If large lots of 1,000 or more, the manufacturer allows a discount of 15%.

Question

Yrly is cheaper by 17.82

Answer 1

First, let's find out how many boxes are needed for a year's supply:

200 Steri-strips per month * 12 months = <<200*12=2400>>2,400 Steri-strips per year.

Now, let's find out how many boxes are needed:

2,400 Steri-strips / 100 per box = <<2400/100=24>>24 boxes.

Now let's find out the cost for 24 boxes without discount:

24 boxes * $4.95 per box = $<<24*4.95=118.8>>118.8.

Now let's find out the discount:

$118.8 * 15% = $<<118.8*0.15=17.82>>17.82.

Now let's find out the cost for 24 boxes with the discount:

$118.8 - $17.82 = $<<118.8-17.82=100.98>>100.98.

Now let's find out the cost of 12 monthly purchases without discount:

$118.8 * 12 = $<<118.8*12=1425.6>>1,425.6.

The yearly purchase with the discount saves:

$1,425.6 - $100.98 = $<<1425.6-100.98=1324.62>>1,324.62.

Therefore, the savings amount to $1,324.62 per year.
