Is (-3-2c)/(-3) the same as (2c+3)/(3)??
(I believe they are the same, but just checking.)

Yes, they're the same.

Step-by-step explanation:

-3-2c can be re-written as -1(2c+3) and -3 can be re-written as -1(3). So you can rewrite the fraction as -1(2c+3)/-1(3). The -1's go away and the new fraction is (2c+3)/3.

to determine the unit cost your would divide the total cost by the number sold.

5 bagels for $3.60         $3.60/5 = $.72 each at value mart
