Final answer:
Felix needs to purchase 24 packs of jerseys to provide two jerseys for each athlete from the basketball, soccer, and football teams at his school.
Step-by-step explanation:
Felix needs to buy two jerseys for each athlete in different sports at his school. To find out how many packs of jerseys he should buy, let's perform the calculation:
- First, calculate the total number of jerseys needed by multiplying the number of players in each sport by two (since each player needs two jerseys):
15 basketball players x 2 jerseys/player = 30 jerseys
23 soccer players x 2 jerseys/player = 46 jerseys
21 football players x 2 jerseys/player = 42 jerseys - Add up the number of jerseys for all sports to get the total:
30 jerseys + 46 jerseys + 42 jerseys = 118 jerseys - Since jerseys are sold in packs of five, divide the total number of jerseys by five to find out how many packs are needed:
118 jerseys / 5 jerseys/pack = 23.6 packs - Because Felix can't buy a fraction of a pack, he needs to round up to the nearest whole number, which means he will need to buy 24 packs of jerseys.
Therefore, Felix should purchase 24 packs of jerseys to have enough for all the athletes.
