Russia's sister gives him two packs of baseball cards per month each pack has 11 card she gave him three extra packs for his birthday how many cards does Richard get in a year

Russia gets 267 baseball cards in a year.

Step-by-step explanation:

Given:

Number of packs given per month = 2

Number of cards in each pack = 11

Number of cards given on his birthday = 3

Now, we know that, there are 12 months in a year.

Using unitary method, the total number of packs given in year and total cards can be calculated. So,

Packs given in 1 month = 2

∴ Packs given in 12 months = 2 * 12 = 24

Number of cards in 1 pack = 11

∴ Number of cards in 24 packs = 11 * 24 = 264

Now, his birthday will come once in a year. So, additional cards received by him will be 3 only. So,

Total number of cards = Number of cards in 24 packs + Additional cards

Total number of cards = 264 + 3 = 267

Therefore, Russia gets 267 baseball cards in a year.
