the best estimate at the end of July = about $ 85
Step-by-step explanation:
Carl puts $1.10 in his penny bank every day in the month of July (31 days)
Amount Put in Penny Bank = 31 * 1.1 = 34.1 $
Saving at the end of June is $55.00
Amount Put in Penny Bank = 34.1 $
Total Amount at end of July = 55 + 34.1 = 89.1 $
Nearest value in given option = $ 85
the best estimate at the end of July = about $ 85
to find estimation
31 day 1.1$
we take 30 day & 1 $ then Saving = 30$
55 + 30 = 85 $
