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?
She spend $56 because 7 x 8 = <<7*8=56>>56
She has $44 left in the bank because 100 - 56 = <<100-56=44>>44
She can get 8 five dollar bills because 44 / 5 = <<44/5=8.8>>8.8
This is equal to $40 because 8 x 5 = <<8*5=40>>40
She has $4 left in the account because 44 - 40 = <<44-40=4>>4
