Mark has $100,000 to invest. His financial consultant advises him to diversify his investment in three types of bonds: short-ter

galina1969 [7]

Answer:

Short-Term investment: 5000$

Intermediate-Term investment: 65000$

Long-Term investment: 30000$

Step-by-step explanation:

To construct our first equation lets define sort-term bond investment as x, long-term investment as y.

So the equation is:

$x*0,04+(100000-x-y)*0,05+y*0,06=5250$

From the equation it is found that:

$y=25000+x$

Instead of y, if we put 25000+x the equation will be as following:

$x*0,04+75000*0,05+(25000+x)*0,06=5250$

From the equation it is found that:

$x=5000$

Short-Term investment is 5000$

$x+25000=y$

Long-Term investment is 30000$

Rest of the money is Intermediate-Term investment 65000$

The equation R=10a-20 represents the revenue R (in dollars) you make by spending A dollars on advertising. You revenue totaled $

timurjin [86]

R = 10a - 20
ur revenue totaled 110...so R = 110

110 = 10a - 20
110 + 20 = 10a
130 = 10a
130/10 = a
13 = a <== so u spent $13 on advertising

How do i estimate quotients 933 divided by 3

Maurinko [17]

K, so
remember that $\frac{a+b+c}{d} = \frac{a}{d}+ \frac{b}{d}+ \frac{c}{d}$
so
$\frac{933}{3}=\frac{900+30+3}{3} = \frac{900}{3}+ \frac{30}{3}+ \frac{3}{3} = 300+10+1=311$
