Final answer:
To find the average amount Tiffany saved per day for the month, divide the sum of her deposits by 30. The average amount she saved per day is $0.70.
Step-by-step explanation:
To find the average amount she saved per day for the month, you need to divide the sum of the deposits by 30.
In this case, Tiffany deposited $6.74, $5.21, $5.53, and $3.52.
The sum of these deposits is $6.74 + $5.21 + $5.53 + $3.52 = $21.
Dividing $21 by 30 will give us the average amount she saved per day: $21 / 30 = $0.70.
Therefore, Tiffany saved an average of $0.70 per day for the month.
