Answer:
There are 20 items on one grocery list and 13 items on second grocery list.
Step-by-step explanation:
We are given that there are two grocery list and one of the grocery list have seven things less than the other grocery list.
Let x be the number of items on one grocery list.
Then, by the given information, there are x -7 items on the second grocery list.
The total number of items on both the list are 33.
Then, according to the question,
[tex]x + (x-7) = 33\\2x - 7 = 33\\2x = 40\\x = 20[/tex]
Thus, there are 20 items on one grocery list and (20 -7) = 13 items on second grocery list.
