Tori is saving up for a new drum for her drum set. The drum costs $235. She started with $115. She made $24.50 more mowing her grandmother's yard. Which equation could be used to find the amount of money, n, Tori still needs to save in order to buy the new drum? n - 115 + 24.50 = 235
115 + 24.50 + n = 235
235 + 24.50 + 115 = n
235 - 115 + 24.50 = n
