Question

Carl puts 1.10$ in his penny bank every day in the month of July (31 days). His total savings was 55.00$ at the end of June. What is the best estimate for Carl's savings at the end of July? (no I did not make a typo)

Answer 1

Hello!

To estimate Carl's savings at the end of the month, we must round the $1.10 Carl puts in his bank to $1 as it is closest to $1, and then multiply that by the number of days in July (31).

1 × 31 = 31

A N S W E R:

The best estimate for Carl's savings at the end of the month of July is $31.
