Answer:

7 pounds of fish
18.5 pounds of lobster

Step-by-step explanation:

Let x represent the number of pounds of lobster sold. Then 25.5-x is the number of pounds of fish. The total money made is ...

4.25(25.5-x) +9.00x = 196.25

4.75x + 108.375 = 196.25 . . . . . simplify

4.75x = 87.875 . . . . . . . . . . . subtract 108.375

x = 18.5 . . . . . . . . . . . . . . . divide by 4.75

The market sold 7 pounds of fish and 18.5 pounds of lobster.

nataly862011 [7]

Answer:

Infant mortality will reduce to 33% in 1.63 years

Step-by-step explanation:

Let the population be X

Population after 1 year

$X - 7.3$ % of $X$

$X -0.073 X\\0.927X$

As we know

$P = P_0 * e^{rt}$

Substituting the given values we get -

$\frac{P_0 - 0.33P_0}{P_0} = e^{-0.33 * t}\\0.67 = e^{-0.33 * t}\\$

Taking log on both sides we get -

$-0.20273 = -0.33 * t\\t = 1.627$
