Question

Hector went shopping for a computer. At RST store, a computer originally prices at $955 had a price reduction of 40%. What was the reduced price?

Answer 1

x 40

------ = --------

955 100

Cross multiply

955x40=38200

38200÷100=382

u get 382

955 -382= 573

$573

Answer 2

Steps

So here are the rules with change by percentage (m = percentage in decimal form, n = original, and r = new):

• If increase: (1 + m)n = r
• If decrease: (1 - m)n = r

Since this is a price reduction, we will be following the second rule. In this case:

`40\%=0.4\\\\(1-0.4)*955=r\\0.6*955=r\\573=r`

Answer:

In short, the reduced price of the computer is $573.
