BTW - the answer is NOT (F) - 22 lb. I tried that, and it was incorrect.

3. dpaInc

do you have the equation that models this problem?

4. dpaInc

the model for this problem is $$\large y=15(1.09)^t$$ , where t is the time in years.

5. BarlowGirl

Oh, I see. So, when I plug 7 into the model, it gives me an approx. answer of: 27 lb. Is this correct?

6. BarlowGirl

Is this correct?

7. TuringTest

If dpalnac is correct about the formula, which I think he is, then the "first year" would be represented mathematically as year 0 (plug in t=0 to get y=15) that means year 7 would be represented as t=6 in your function...

8. BarlowGirl

Oh, I see. Okay. That's what I thought. So then, if it was t=6, then it would be 25 pounds of honey.

9. TuringTest

seems that way, but the wording leaves me unable to say that we have interpreted the problem correctly for certain. I get 25 as well though...

10. TuringTest

I can only hope I am reading the problem right

11. BarlowGirl

Sure, I understand. Thank you very much for trying! :)

12. TuringTest

just following the logic step-by-step$\text{year1}\implies15$$\text{year2}\implies15(1.09)$$\text{year3}\implies15(1.09)^2$so it should be$\text{year7}\implies15(1.09)^6$so I think we got it :)

13. BarlowGirl

Perfect, thank you so much! :)

14. TuringTest

welcome!

i agree... the wording is .... bleah!
