Question

On the first day of​ June, there were about 17.86 h of daylight in a city. Five months​ later, there were about 8.40 h of daylight. What was the percent​ decrease?​(Round to the nearest whole number as​ needed.)

Answer 1

The percent decrease is 53%

Step-by-step explanation:

The percent decrease is given by:

$Percent-Decrease = \frac{Old\ value-New\ value}{Old\ value} * 100$

Here

Old Value = 17.86 hours

New Value = 8.40 hours

So,

$Percent-Decrease = \frac{17.86-8.40}{17.86}*100\\=\frac{9.46}{17.86}*100\\=0.5296*100\\=52.96\%$

Rounding off to nearest whole number

53%

So,

The percent decrease is 53%
