Explanation:
Jayden jars jams at a rate of 6 liters per day which can be represented by the variable
. In other words, the amount of jam Jayden will have made in the end (j) is 6 liters multiplied by the number of days (d) he spent jarring jam.
However, Jayden has already jarred 1 liter of jam which has to be factored into the end total (j). To factor this liter in, you can add 1 (liter) to 6d.
