Answer:

  1. 12-pack -- lower unit cost
  2. $0.02 per can

Step-by-step explanation:

1) The cost per can is the cost divided by the number of cans.

  $4.44/(12 cans) = $0.37/can . . . . . unit cost for 12-pack

  $7.80/(20 cans) = $0.39/can . . . . unit cost for 20-pack

The 12-pack has a lower unit cost per can. Mitch should choose the 12-pack.

__

2) The difference in cost per can is ...

  $0.39 -0.37 = $0.02 . . . per can
