it says. For each of the following values of b in an equation of the form y=a.b, . Determine the growth rate per time period. they are 1.2 , 2.4 , 1.07 , 1+0.33, 1.259. 1.002.
I know that b is 1+ percent growth. and i also know that the answer for 1.2 is 20% and the answer for 1.002 is 2%. My teacher told us that..but im still not sure how to do it. help would be really appreciated!

I used to teach math, and I am totally confused by this question. What is the equation? y =a.b ? That doesn't make much sense.
My guess is this: That the growth rate is 100% (or 1) + rate of change (which is b, I think). Therefore, 1.2 would be 20% because it is 1 + .2 (.2=20%). On this line of thinking, 1.02 is 2% because it is 1 + .02 (.02 is 2%). Therefore, to find answer, all you do is subtract 1 and then change the remaining number into a percent by multiplying it by 100.
This makes sense because if something wouldn't grow at all, it would be multiplied by 1 or 100%. If it grew by 5%, you would multiply by 105% (the 100% original size plus a 5% increase). That is, if an object grew by 5%, you would multiply its original size by 105% or 1.05.
I hope that helps.
