Carolyn will buy the same number stamps every month to ask her stamp collection her grandfather gave her the table shows the number of stamps carolyn will have at the end of the x months how many stamps was clearly given and how many stamps will she buy every month

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.
