Save That Money!

Algebra Level pending

Hsu decides to save some money to buy a new phone. He does not know how much the phone is, so he wants to save money throughout January. He will save 1 cent on January \(1^{st}\), 4 cents for the \(2^{nd}\) day, 10 cents on the \(3^{rd}\) day, 19 cents on the following day, 31 cents on the \(5^{th}\) day, and so on for the month. How much money will Hsu have saved in January?

Express your answer in dollars and cents (Ex. $178.82 would be inputted as 178.82)


  • January has 31 days

  • He does not save any other money not stated in the problem

  • Don't bash it!
