Pls Help

Answer 1

Percent decrease is 21.7%

Explanation:

The percent decrease is calculated as:

`Decrease\ percentage = (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 = (decrease)/(Travelling\ cost\ in\ November) * 100\\=(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%
