In summary, to determine the number of marbles and stamps Casey bought, you can use the equation M + S = T, where M represents the number of marbles, S represents the number of stamps, and T represents the total number of items purchased. To solve this problem, you will need to know the total amount spent by Casey, the price of each marble and stamp, and the ratio of marbles to stamps purchased. There is a specific formula for solving this problem, which is M + S = T. Any unit of measurement can be used for the number of marbles and stamps as long as they are consistent. Lastly, you can use the same equation to solve similar problems as long as the variables represent the same quantities,

I have a question

Carey bought some marbles and gave half of them to Casey. Casey bought some stamps and gave half of them to Carey. Carey used 5 stamps and Casey gave away 11 marbles. The ratio of the number of stamps to the number of marbles Carey had left then became 1 : 7 and the ratio of the number of stamps to the number of marbles Casey had left became 1 : 5. How many stamps did Casey buy?
