344

Step-by-step explanation:

Number of coins added per day in the collection = 9

Number of coins in the collection after 22 days = 218

To find:

Number of coins in the collection after 36 days.

Solution:

First of all, let us find how many coins did he have initially.

Let the number of coins present initially with Wil =

Number of coins added per day = 9

Number of coins added after 22 days = 22 9 = 198

Therefore,

Number of coins present with Wil initially = 20

Number of coins added after 36 days = 36 9 = 324

Total number of coins after 36 days = Number of coins present initially with Will + Number of coins added = 324 + 20 = 344
