Answer: <em>Multiply the original price by the decimal form of the percent and subtract that from the original price.
</em>
<em>37*0.85=31.45
</em>
<em>37-31.45=5.55
</em>
<u><em>Answer: New price is $5.55</em></u>
The estimate for the total population size is 1600.
Setting up a proportion for this, we know that 150 out of our 300 turtle sample is marked; this is the first ratio for the proportion. We also know that we marked 800 of our total population, which we will call x:
150/300 = 800/x
Cross multiply:
150*x = 300*800
150x = 240000
Divide both sides by 150:
150x/150 = 240000/150
x = 1600
