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=(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%
