Emma's bank account has $100 in it. Each day of the week, she spends $8. At the end of the week, she goes to the bank and asks for as many $5 bills as her account can give her. She leaves the rest in the account. How many dollars remain in the account?
Thoughts? Step-by-step reasoning:
She spend $56 because 7 x 8 = 56. She has $44 left in the bank because 100 - 56 = 44. She can get 8 five dollar bills because 44 / 5 = 8.8. This is equal to $40 because 8 x 5 = 40. She has $4 left in the account because 44 - 40 = 4.
Thus, the answer is 4.
