Answer 1

Answer:

Percent decrease is 21.7%

Step-by-step explanation:

The percent decrease is calculated as:

$Decrease\ percentage = \frac{decrease}{Original\ quantity} * 100$

Given in the question that:

Cost on travel during November = $83

Cost on travel during December = $65

The percent decrease will be calculated by computing decrease(subtracting the cost of December from the cost of November.

$Decrease = Travel\ cost\ in\ November - Travel\ cost\ in\ december\\Decrease = \ 83-\ 65\\= \ 18$

Now, for percentage decrease

$Percentage\ decrease = \frac{decrease}{Travelling\ cost\ in\ November} * 100\\=\frac{18}{83} * 100\\=21.686..$

Rounding off to nearest tenth of percent, we get the percentage decrease as 21.7%

Hence,

Percent decrease is 21.7%
