Answer:

less value

Step-by-step explanation:

To deterimine if value was improved or not, we need to compare the price reduction to the size reduction.

The reduction in price is ...

((new value)/(old value) -1) × 100%

= (42/50 -1) × 100% = -16%

The size reduction of 20% is more than the price reduction of 16%, so the chocolate bar is <em>less value</em>.

_____

<em>Additional comment</em>

Compared to the original value, the new price to chocolate ratio is ...

0.84/0.80 = 1.05

Effectively, the price was raised by 5%.

Answer:

Jaylen's conclusion is a valid conclusion because it is logical

Step-by-step explanation:

Jaylen's conclusion is a valid conclusion because it is logical. Regardless of not having all the necessary information needed to prove that the number of dogs is the sole main cause for an increase in cleaner usage she can still conclude this. Since dogs naturally bring in dirt from outside and make messes, and since Jaylene notices that families that are known to have more dogs are buying more floor cleaner then she can logically come to this conclusion.
