Question

Polly has already jarred 13 liters of jam and will jar an additional 1 liter of jam every day. How many days does Polly need to spend making jam if she wants to jar 22 liters of jam in all?

Answer 1

Polly needs to spend 9 additional days making jam to reach her goal of 22 liters, as she has already jarred 13 liters and will jar an additional 1 liter each day.

Step-by-step explanation:

The student's question about Polly's jam-making can be solved using a simple arithmetic calculation. Polly has already jarred 13 liters of jam and will jar an additional 1 liter of jam every day. If she wants to jar a total of 22 liters of jam, we need to determine the number of additional days required to reach this total.

First, we calculate the difference between the goal (22 liters) and what has already been jarred (13 liters):

1. 22 liters (total goal) - 13 liters (already jarred) = 9 liters remaining.
2. Since Polly jars 1 liter per day, we divide the remaining liters by the daily production:
3. 9 liters divided by 1 liter/day = 9 days.

Therefore, Polly needs to spend 9 additional days making jam to meet her goal of 22 liters of jam in all.
