Cory's roses grow around 1 inch each month. When he planted them they were 6 inches tall.

What is the initial value for the scenario described?

12

r=12 as answer but as you will have reflective numbers (r12+2) (10x10) = 3 in this sort of equation you will see that as they grew at a 88.3% rate 5/6 and 0.16 is a per month rate the coefficient value we can round down and call r12 = 6 for step 2 in the equation. As we can also find + 0.88 which rounds to 1 and 0.33 the rate of change per month rounds to - 1 and - 100/12=8.3 if you are looking for the percentage. To find 6 we only need to 10/10 = 1. It is important you keep an equation simple for the growth as the change in measurement will always need a new percentage and we have a base number that can show such percentage as if it changed to 100% again at 12 inches we could reuse the equation = 3-2=1 etc. or r12/100 = 0.88 r=rise percentage and also be divided into 2 if we call r12 and r2 in same first equation to make r6.
