Final answer:
The average amount Mckenna saved per day last month is $0.70, calculated by summing her deposits and dividing by 30 days.
Step-by-step explanation:
To find out the average amount Mckenna saved per day last month, we first need to sum up the amounts she deposited in her savings account. These amounts are $6.74, $5.21, $5.53, and $3.52. The total sum is:
$6.74 + $5.21 + $5.53 + $3.52 = $21.00
To calculate the average saved per day over the 30-day month, we divide the total amount saved by 30:
$21.00 รท 30 = $0.70
Therefore, the average amount Mckenna saved per day for the month is $0.70.
To find the average amount McKenna saved per day for the month, we need to add up all the amounts she deposited and then divide by 30 (the number of days in a month).
The sum of the amounts is: 6.74 + 5.21 + 5.53 + 3.52 = 21
So, the average amount she saved per day is: 21 / 30 = 0.7
Therefore, McKenna saved an average of $0.70 per day for the month.
