At the start of an adventure game, Ralph had 100 coins. At the end of the game, he had 415 coins. Ralph earned 45 coins for each successful mission. Assuming he did not lose or spend any coins, solving which equation will show how many successful missions Ralph completed?

Respuesta :

Answer: Ralp has completed 7 successive rounds

Explanation:

The initial amount Raph has was 100 coin

The final amount he had was 415 coin

The difference is (415-100) = 315coin.

Since every successive round won by raph yields him 45coins, therefore,

Ralph had won 315/45 rounds = 7 rounds.
