Final answer:
To find the average amount of money Jack has in his pocket during the week, add up the amount of money he has each day and divide that sum by the number of days in the week. The average amount is $7.
Step-by-step explanation:
To find the average amount of money Jack has in his pocket during the week, we need to add up the amount of money he has each day and then divide that sum by the number of days in the week.
Monday: $12
Tuesday: $3
Wednesday: $10
Thursday: $8
Friday: $2
Total = $12 + $3 + $10 + $8 + $2 = $35
Since there are 5 days in a week, we divide the total amount by 5: $35 ÷ 5 = $7
Therefore, the average amount of money Jack has in his pocket during the week is $7.
