Question

The value of the function y= (3/5)t decrease by what percentage of t increases by 1 unit

Answer 1

Percent of decrease in the value is 40%.

Explanation:

Let's find the value of y when t=1 and t=2 because need to find the decrease by percent of t increases by 1 unit.

When t=1

y=
`(3)/(5)^(1)`=0.6

When t=2

y=
`(3)/(5) ^(2)` =0.36

Percent of decrease = 100 % -
`(0.36)/(0.6)*100%`% = 100% -60% =40%
