Mrs. Delgado purchased notebooks at 2 for $5 and pens

at $2 per package. She spent $19 for a total of 8 items.

How many notebooks and pens did she buy?

Answer 1

Mrs. Delgado purchased 6 notebooks and 2 packages of pens.

Explanation:

Given that Mrs. Delgado purchased notebooks at 2 for $ 5 and pens at $ 2 per package, and she spent $ 19 for a total of 8 items, to determine how many notebooks and pens did she buy the following calculation must be performed:

5/2 = 2.5

8 x 2.5 + 0 x 2 = 20

6 x 2.5 + 2 x 2 = 19

Therefore, Mrs. Delgado purchased 6 notebooks and 2 packages of pens.
