Question

The number of cars at a dealership dropped from 64 to 48 after a weekend sale. What is the percent of decrease in the number of cars?

Answer 1

No. of cars dropped from 64 to 48
No. of cars before= 64
No cars after weekend sale= 48
Percentage decrease
\[\frac{64-48}{64} \times 100=\frac{16}{64} \times 100\]
\[= \frac{\cancel{16} 1}{\cancel{64} 4} \times 100= 25 \%\]

Answer 2

one percent of 64 = 0.64
one houndred percent of 64 = 64
so 100 times 0.64 = 64
then for 48 cars we want
percentage times 0.64 = 48
or percentage = 48 divided by 0.64
then 48 is 75% of 64 and the decrease in percentages is 25
