Weve been learning about exponential equations in class (Imp 3). We were asigned a POW (problem of th week) about rats:
A male and female rat get stuck on an island in late Decemer. She gives birth on January 1st to a litter of 6, and will continue to give birth every 40 days. Every litter will always have six pups: three males and three females. Each female (the daughter rats) will produce a liter 120 days after birth, and will continue to reproduce every 40 days.
Find the number of rats after one year (the following January 1st), including the orginal pair.
I attempted to draw out the situation, but stopped after 7 rows or generations because I was so confused. I know you can do this with an equation or a graph....i think. Can anyone help?
