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.
8 times 18 is 144. then take that and divide it by 60 seconds which equals a minute. your answer is 2 minutes and 40 seconds
60000(0.081)10+60000=$108600
60000(.1)+60000(.0665)(10)+60000=$105900
