Answer:
a.) .375 inches per day
b.) no
c.) 48 days
Explanation:
If 8 days produces 3 inches of ice, I divided the 3 inches by the 8 days to see how much it grew per day. I got .375 inches per day.
Knowing how much it grew each day, I used .375 inches per day and multiplied it by 21 (3 weeks). So no, it only grew 7.875 inches over the 21 days.
You can double check it by dividing 10 inches / .375 inches per day and saw it would take over 26 days to reach 10 inches.
I took 1.5 feet and converted it to 18 inches. 18 inches divided by .375 inches per day equals 48 days.
I hope this helps you! :)
