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%.

ivann1987 [24]

First, we need to add all of the dollar amounts to get the total the civic group needs to raise.

Then, divide by number of tickets.

$4,000/1,000=$4
