Step-by-step explanation:

For number 5 the answer would be economy because there is a 2 dollar difference and the shampoo bottle has 20 more ounces then the regular bottle. The 2 dollar difference changes the whole thing.

For number 6 the answer is still economy because you get more ounces in the bottle of shampoo for a 3 dollar difference in the price.

BTW HOPE YOU HAVE AN AMAZING DAY!!!
