Question

What is the decay factor that corresponds to a 35% decrease?

0.35
C. 0.65
0. 35
d. 65

Answer 1

0.65

Explanation:

To reduce a quantity by 35%, multiply it by 100% - 35% = 65% = 0.65

Think of it like this: if 35% of a quantity is gone, 65% remains.

This applies to all sorts of situations. One example is discount or sale prices.

A $250 item goes on sale at a 35% discount. The sale price is 0.65 x 250 = 162.5 ($162.50). If you DON'T pay 35% of something, you DO pay 65%.
