You can set up this question as an amount of flowers as a function of weeks: F=rt, where F=amount of flowers, t=weeks, and r=rate.
Inserting the first pair of values (9 flowers and 2 weeks), you get: 9=r(2)
Dividing both sides by 2 gives you: r=9/2=4.5 flowers per week
Now that we know what r equals, we can substitute F for 500 flowers, giving you: 500=(4.5)t
Dividing both sides by 4.5 gives you: t=500/4.5=111.11 weeks
It would take you 111.11 weeks to grow 500 flowers
