Natasha2012 [34]

Answer:

$X=\$1.64*10^9$

Step-by-step explanation:

From the question we are told that:

Population size $P=918000$

Rate of Population increase $\frac{dP}{dt}=9700$

Average annual income $I= \$34,549$

Rate of annual income increase $\frac{dI}{dt}=\$1300$

Generally the equation for Total Income is mathematically given by

$X=P \frac{dI}{dt}+I \frac{dP}{dt}$

$X=918000*1400+(9200*30593)$

$X=\$1.64*10^9$

The ticket sales for Fist Bump are as follows:

Fed [463]

Notice that the denominators are 3 and 7, which are factors of 21.

So express all the fractions with denominator 21:

On Monday $\frac{1}{7} = \frac{1}{7} * \frac{3}{3} = \frac{3}{21}$ are sold
On Tuesday $\frac{1}{3} = \frac{1}{3} * \frac{7}{7} = \frac{7}{21}$ are sold
On Wednesday $\frac{2}{7} = \frac{2}{7} * \frac{3}{3} = \frac{6}{21}$ are sold

by Thursday $\frac{3}{21}+\frac{7}{21}+\frac{6}{21} = \frac{3+7+6}{21}= \frac{16}{21}$ of the tickets was sold.

Answer: $\frac{16}{21}$
