Modelling Linear Growth and Decay (VCE SSCE General Mathematics): Flashcards

Quantity increases by same fixed amount over equal time periods

Quantity decreases by same fixed amount over equal time periods

Constant amount added or subtracted at each step

$V_{n+1} = V_n + D$

$V_{n+1} = V_n - D$

Initial amount of money borrowed or invested

D = rac{r}{100} imes V_0

Decrease in value of an asset over time

D = rac{r}{100} imes V_0

Value loss based on how often asset is used, not time
