Answer:
y=7* (0.5)^x
Step-by-step explanation:
We are given that when x increases from 'a' to 'a+2' then y must increase by a factor of 1/4=0.25.
i.e. when x=a and x'=a+2.
then y/y=0.25 where y' is the function after putting x' to the old function.
First divided 140 by 100 to find out how much 1 percent is
140 ÷ 100 = 1.4
multiply 1.4 by 45 to find 45 %; 1.4 x 45 = 63
then add 63, which is 45%, to 140, which is 100%, and you get 203, which is 140 + 45%, or 145%
