Grade 5 and 6 collect 12 times as many cans as grades 1 and 2. Grades 3 and 4 I collect 6683 cans, and that amount is 2389 cans less than great 5 and 6. How many cans are collected by grades 5 and 6?

Answer: 9072

Step-by-step explanation:

It seems that the number of cans that grades 1 and 2 collect are irrelevant in the problem so you can basically ignore that. Grades 3 and 4 have 6683 cans which is 2389 cans less than grades 5 and 6 so that means grades 5 and 6 have 2389 cans more than 6683. Now you just add 6683 and 2389 to find the cans that grades 5 and 6 have.

6683 + 2389 = 9072

Grades 5 and 6 have 9072 cans
