If the cost of 2 score pens is 280, then the cost of 2 dozen pens will be?

2score=40

2dozen=24
so, the cost will be

24/40 * 280

156

To find the cost of 2 dozen pens, we first need to understand the relationship between a score and a dozen.

A score is a unit of measurement that represents 20. So "2 score pens" means 2 times 20 pens, which is equal to 40 pens.

Now, since a dozen represents 12, we can calculate the cost of 2 dozen pens by multiplying the cost of one pen by the total number of pens.

Let's assume that the cost of one pen is "x."

If 40 pens cost 280, we can set up the following equation:

40 pens = $280
1 pen = $280/40

Now, to find the cost of 2 dozen pens, we multiply the cost of one pen by the total number of pens:

2 dozen pens = 2 * 12 = 24 pens

Therefore, the cost of 2 dozen pens will be:

2 dozen pens = 24 pens * (cost of 1 pen)
= 24 * (280/40)
= 24 * 7
= $168

Therefore, the cost of 2 dozen pens will be $168.
