The population of a small town is 40,740. It's population falls by 8% per year. How many years later will the population be 14,5
Mashutka [201]

Answer:

0.9101523758 ≈ 1 year

Step-by-step explanation:

The population of a small town is 40,740.

Its population falls by 8% per year.

Given: Compound interest Amount (A) = P( 1 + \frac{r}{n})^{nt}

14,550 = 40,740(1 + \frac{-8}{100 * 1})^{t*1}

14,550 = (40,740 - 3259.2)^{t}

14,550 = (37,480.8)^{t}

t * log 37,480.8 = log 14,550

t = \frac{ log 14,550}{log 37,480.8} = 0.9101523758 ≈ 1 year

                   $420                       $182

        $32.85 + $420 + $182 = $634.85 per year

Al bought 24 stickers. He gave away 11 stickers. Then he bought 8 more stickers.
Yakvenalex [24]
24-11+8

He BOUGHT 24 stickers, so you'd write 24. Then because he GAVE AWAY 11 stickers, you would subtract 11 from 24, which is 24-11. Then because Al BOUGHT 8 stickers you'd add the 8 to the 24-11 to get 24-11+8.


(Bought means to add and Gave away is subtracting)
