Carolyn will buy the same number stamps every month to ask her stamp collection her grandfather gave her the table shows the num

pochemuha

The answer is A.

She had 250 after 1 month, and 350 after 3 months, so 350-250=100.

Divide 100 by 2 because it took her 2 months to get 100. 100/2= 50

She buys 50 stamps a month.

So if she has 250 after 1 month, you need to subtract 50 to get the 200 stamps given to her by her grandpa.
