Question

how do i do these two. irene bought a typewriter at rocklanes in 1988 for $200.In 1999, she bought the same model of typewriter for $120.What is the percent decrease in the price of the typewriter. denise bought a typewriter at rocklanes in 1984 for $500. In 2000 , she bought the same model of typewriter for $440. What is the percent decrease in the price of the typewriter?

Percent decrease = 100 x (Original Price - Current Price) / (Original Price)

In the first question, that is (200-120)/200 x 100 = 40%

Answer 1

To find the percent decrease in the price of the typewriter, you can use the formula:

Percent decrease = 100 x (Original Price - Current Price) / (Original Price)

Let's apply this formula to the first question:

Irene bought a typewriter at Rocklanes in 1988 for $200. In 1999, she bought the same model of typewriter for $120.

Plugging the numbers into the formula:

Percent decrease = 100 x (200 - 120) / 200
Percent decrease = 100 x 80 / 200
Percent decrease = 40

Therefore, the percent decrease in the price of the typewriter for Irene is 40%.

To solve the second question:

Denise bought a typewriter at Rocklanes in 1984 for $500. In 2000, she bought the same model of typewriter for $440.

Plugging the numbers into the formula:

Percent decrease = 100 x (500 - 440) / 500
Percent decrease = 100 x 60 / 500
Percent decrease = 12

Therefore, the percent decrease in the price of the typewriter for Denise is 12%.
