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

FrozenT [24]

Answer:

No, the student is not correct. The correct expression is 9(n+13).

Step-by-step explanation:

"9 times the sum of a number and 13" means you must multiply 9 by the sum, not just by the number. 9n + 13 would be "the sum of 9 times a number and 13." Slightly different wording.
