Answer: $6.4
Explanation:
Total money = $80
She spends 3/5 of the money on Monday , means that she spends
3/5 x 80 = $48
That means she spent $48 on Monday , the remainder will be
$80 - $48 = 32
Since she spend the remaining money equally over 5 days , this means that she will spend 32/5 each day.
Therefore , she spent $6.4 each of the five days
