Two partners agree to invest equal amounts in their business. One will contribute $10,000 immediately. The other plans to contr

krek1111 [17]

Answer:

She should contribute $ 8369.38 ( approx )

Step-by-step explanation:

Let P be the amount invested by the other partner,

∵ The amount formula in compound interest,

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

Where,

r = annual rate,

n = number of compounding periods in a year,

t = number of years,

Here, r = 9% = 0.09, n = 4 ( quarters in a year ), t = 2 years,

Then the amount after 2 years,

$A = P(1+\frac{0.09}{4})^{8}$

According to the question,

A = $ 10,000,

$P(1+\frac{0.09}{4})^{8}= 10000$

$P(1+0.0225)^8 = 10000$

$\implies P = \frac{10000}{1.0225^8}\approx \$ 8369.38$

Kira reasoned that 6 1/4 - 2 3/4 = 4 2/4 because the difference between 6 and 2 is 4 and the difference between 1/4 and 3/4 is 2

xeze [42]

<span>Yes, she is reasoning correct, because:

6 1/4 and 2 3/4 are mixed fractions and you can substract them as it shown below:

1. You must substract the fractional parts (</span>which are: 1/4 and 3/4) of the mixed fractions. You can notice that the have the same denominator "4", so you only need write this denominaro and substract the numerators:

= (1-3)/4=-2/4

When you simplify the result, you obtain:

=-1/2

Now, you must sum the integer parts:

6-2=4

Finally, you obtain:

4 -1/2
