Answer 3

Calculating the Number of Magazines

To calculate the number of magazines about cars in each pack, we can use the information provided.

Given: - Total number of magazines = 430 - Magazines about fashion were packed in 30 packs, with 9 magazines in each pack. - Magazines about cars were packed in 20 identical packs.

Solution

1. Calculate the total number of fashion magazines: - Total fashion magazines = 30 packs * 9 magazines/pack = 270 magazines

2. Calculate the total number of car magazines: - Total car magazines = 430 total magazines - 270 fashion magazines = 160 magazines

3. Calculate the number of car magazines in each pack: - Number of car magazines in each pack = Total car magazines / Number of packs - Number of car magazines in each pack = 160 magazines / 20 packs = 8 magazines/pack

Therefore, there were 8 magazines about cars in each pack.
