Answer:

One Solution

Step-by-step explanation:

First substitute the y in the first equation with the second equation to get

-2x-4=3x+3

since theres a variable of both sides, you subtract the variable with the least coefficient, in this case, you add 2x to both sides to get

-4=5x+3

subtract the constant on both sides to get

-1=5x

divide both sides by 5

x= -0.2 or -1/5

Great Dish believes that it will need new equipment in 8 years. The equipment will cost $26,000. What lump sum should be investe

xenn [34]

Answer:

d. $10,234.80

Step-by-step explanation:

we are given

The equipment will cost $26,000

so, Amount is $26000

A=26000

should be invested today at 12%

r=12%=0.12

It is compounded semiannually

so, n=2

t=8

now, we can use formula

$A=P(1+\frac{r}{n})^{nt}$

now, we can plug values

$26000=P(1+\frac{0.12}{2})^{2\times 8}$

now, we can solve for P

$P=10234.80338$
