Question

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

The answer I got was: 7x + 100 = 415 but I am not sure if that is correct?

Answer 1

X is the number of missions completed.

100 + 45x = 415

45x = 315

x = 7
