On the first day of June, there were about 17.71 h of daylight in a city. Five months later, there were about 5.3 h of daylight. What was the percent decrease?

To find percentage decrease of 2 quantities, we have to find the difference of the quantities and divide by the original quanity. Then we multiply by 100 to find the PERCENTAGE.

We will use formula:

[tex]\frac{New-Old}{Old}*100[/tex]

Where

"New" is the latest quantity

"Old" is the first (previous) quantity

Here, New = 5.3 & Old = 17.71

We substitute into formula and find:

[tex]\frac{New-Old}{Old}*100\\=\frac{5.3-17.71}{17.71}*100\\=-0.700*100\\=-70[/tex]

So we can say that the percentage decrease is 70%
