The life expectancy of a circulating coin is years. The life expectancy of a circulating dollar bill is only 1/20 as long. Find the life expectancy of circulating paper money.

1/20 as long as a coin

Step-by-step explanation:

Because paper money is dollar bill.

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p
