Answer:
Initial population is 2,466,000 ( p0 )
Growth is 1.1% each year ( r=1.1
p(t)=p0(1+r)t
After 30 years, the population of Jamaica should be 3.42 million by that calculation, but it is only 2.95 million, so apparently that growth rate was a little high, or wasn’t sustained.
The total amount of the resulting mixture can be calculated by adding up the volume of the given substances assuming that volume addition is applicable given the properties of the fluids used.
That is,
T = 6 quarts + 10 quarts = 16 quarts
The total volume of the resulting mixture is 16.
Then, we do the component (antifreeze) balance by adding up the resulting antifreeze from the substances to the total. We let x be the percentage of antifreeze in the final mixture.
6(0.52) + 10(0.32) = 16(x)
The value of x from the equation is 0.395.
Therefore, the answer to this item is 39.5%.
