Question

The local pharmacist sells a tin of 25 aspirin for 40 cents and a bottle of 100 aspirins for $1.50. What is the amount saved when purchasing 1000 aspirin in quantities of 100 instead of quantities of 25?

Answer 1

You have $1 for buying 100 instead of 25

Answer 2

$1.00.

Step-by-step explanation:

Let's compare the cost of purchasing 1000 aspirin in quantities of 25 versus quantities of 100.

• For quantities of 25 aspirin:
• Cost of 25 aspirin = 40 cents

Purchase Cost of 1000 aspirin (in quantities of 25)

`\sf = 40 cents * (1000 )/( 25) = 40\: cents * 40 = 16.00`

For quantities of 100 aspirin:

• Cost of 100 aspirin = $1.50

Cost of 1000 aspirin (in quantities of 100)

`\sf = 1.50 * (1000 )/( 100) = 1.50 * 10 = 15.00`

Now, let's calculate the amount saved when purchasing in quantities of 100 instead of quantities of 25:

We get amount saved by subtracting Cost when purchasing in quantities of 25 by cost when purchasing in quantities of 100

`\sf \textsf{Amount saved }= 16.00 - 15.00`

`\sf \textsf{Amount saved }= 1.00`

Therefore, the amount saved when purchasing 1000 aspirin in quantities of 100 instead of quantities of 25 is $1.00.
