Ms. coleman's class has already collected 403 cans for a food drive, but the class wants to collect a total of at least 1,000 cans. if each of the 28 students in the class brings an equal number of cans, how many more cans should each student bring for the class to have collected at least 1,000 cans?

We need to figure out how many more cans they need to bring.  We figure this out by subtracting 403 from 1,000, which gives us 596 more cans.  We now divide 596/28, to find how many each student would need to bring.  This equals 21.3.  You might want to mention that each student can't bring .3 of a can, so the answer could be 22 also.
