Question

joys plant was 3 inches tall. now it is 8 inches tall. How much did her plant grow. how much will grow in 2 weeks.

Answer 1

IT grew 5 inches and that is alot.

Assuming it continues to grow 5 inches per week it will be 13 inches next week.

 

This is a LINEAR model, assuming the growth rate does not change over time.

Otherwise it is an exponential model.
