Question

A big-screen TV that previously sold for $2,400 has been marked
down to $2,040. What is the percent of decrease?

Answer 1

Answer:

the percent of the difference is the rate of the difference * 100%

the percent of the difference = .15 * 100% = 15%

since the new price is less than the old price, that is the percent of the decrease.

Answer 2

The percent of decrease is 15.

Given,

Old price = 2400

New price = 2040

Difference = 2400 - 2040 = 360

Difference divided by old price = 360 / 2400 * 100 = 15%

What is problem-solving?

Problem-solving is the act of defining a problem; figuring out the purpose of the trouble; identifying, prioritizing, and selecting alternatives for an answer; and imposing an answer.

Problem-solving starts with identifying the issue. As an example, a trainer may need to parent out a way to improve a scholar's overall performance on a writing talent test. To do that, the instructor will overview the writing exams looking for regions for improvement.
