which set of expo pens has a cheaper price the set of 8 which cost in total 11.57$ or the set of 4 which is 4.49

the 4.49 ones.

Step-by-step explanation:

11.57 divided by 8 would result in each pen costing 1.44$ per pen. Meanwhile, dividing 4.49 by 4 would result in each pen costing 1.12$.

The second deal is cheaper

Explanation:

We're looking for the unit cost, which is the cost for one item (in this case, it's the cost of one pen). To get the unit cost, divide the total cost over the number of pens.

For the first deal, we have a unit cost of 11.57/8 = 1.44625 which rounds to 1.45 dollars.

The unit cost for the second deal is 4.49/4 = 1.1225 which rounds to 1.12 dollars. The second deal is the cheaper option due to 1.12 being smaller than 1.45
