Question

The price of the video camera dropped from $1120 to $896. What percent decrease does this price drop represent?

Answer 1

start by writing a relation between the price and the percentages

Solve the relation to find the percentage corresponding to $896

$x=\frac{896\cdot100}{1120}$$x=80$

if x=80% means that the percent decrease is the difference between the percentages

$100-80=20$

the percent decrease was 20%
