Greg's daughter will have $533 in her piggy bank in a year
The money in the piggy bank would increase everyday by the amount put in it. There are seven days in a week. If he puts $0.75 everyday apart from on Sundays when we puts $5.75, the amount that would be in the piggy bank in a week is the sum of the money deposited each day.
Total amount in a week = total amount deposited from Monday to Saturday + amount deposited on Sunday
- Amount that Greg puts in 6 days : ($0.75 x 6) = $4.50
- Amount deposited on Sunday = $5.75
- Total amount = $5.75 + $4.50 = $10.25
The total amount Greg's daughter would have in a year is a function of the number of weeks in year and the total amount saved in a week
Total amount in a year = number of weeks in year x the total amount saved in a week
- Number of weeks in year = 52
- The total amount saved in a week = $10.25
$10.25 x 52 = $533
In order to determine how much Greg's daughter would have in a year, first determine how much she would have in a week. Multiply this amount by the number of weeks in a year
