Aimi is making Valentine's Day cards for everyone in her class. She plans to use a whole sheet of paper for each of her 5 closest friends. She will use 1/2 of a sheet of paper for everyone else in the class. She has 15 sheets of paper. How many cards can she make?

5 + 2*10 = 25

To solve this problem, we need to determine the number of cards that Aimi can make using the given information.

First, let's calculate the number of cards Aimi can make for her 5 closest friends. Aimi plans to use a whole sheet of paper for each of them. Since she has 5 closest friends, she will need 5 sheets of paper for them.

Next, we need to calculate the number of cards Aimi can make for everyone else in the class. Aimi plans to use 1/2 of a sheet of paper for each person. We know that Aimi has 15 sheets of paper in total, and she needs 5 sheets of paper for her closest friends. So, she has 15 - 5 = 10 sheets of paper remaining for everyone else.

Since Aimi can make 1/2 of a card with each sheet of paper, we can multiply the remaining number of sheets (10) by 1/2 to get the number of cards she can make for everyone else.

10 sheets * 1/2 card per sheet = 10/2 cards = 5 cards

Therefore, Aimi can make a total of 5 cards for everyone else in the class.

Finally, we can calculate the total number of cards Aimi can make by adding the cards she can make for her closest friends and everyone else.

Number of cards for closest friends + Number of cards for everyone else = Total number of cards
5 cards (closest friends) + 5 cards (everyone else) = 10 cards

Therefore, Aimi can make a total of 10 cards for Valentine's Day.
