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 less value.

Additional comment

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%.

antoniya [11.8K]

Answer:

No, the note papers will not fit the gift box.

Step-by-step explanation:

Given that:

Volume of the gift box = 64 $in^3$

Length, width and height of the box all are equal to $y$ inches.

Dimensions of note papers = 6 inch by 6 inch

To determine:

Whether the note papers will fit the bottom of the box?

Solution:

Here, we need to find the dimensions of the gift box first.

If the dimensions of gift box are greater than or equal to the dimensions of the note papers, only then the papers will fit into the box.

As per the given question statement, the gift box is in the form of a cube.

Formula for volume of a cube is given as:

$Volume = (Side)^3$

Side is given equal to $y$ inches.

$64 = y^3\\\Rightarrow y = 4\ in$

Dimensions of the box are lesser than that of the note papers.

Therefore, the note papers will not fit into the gift box.
