Suppose you invest $750.00 in a fund earning 6% simple discount. A certain time later you withdraw the investment (principal and
barxatty [35]

Answer:

4.08 + 2 = 6.08 years

Step-by-step explanation:

we know that

Simple Interest(S.I.) = (P × R × T) ÷ 100

where, P = Principal = 750

R = Rate = 6%

T = unknown

⇒ S.I. = (750 × 6 × t)÷ 100

⇒ S.I. = 45t

Also, Amount = S.I + Principal

⇒ Amount = 750 + 45t

Now Formula for Compound Interest is:

A = P(1+\frac{r}{100})^{t}

where A = Amount

=1000

P = Principle

r = rate

t = total number of year

Here, P = 750 + 45t, r = 3.5% , and t = 2.

Putting all these values in above formula:

1000 = (750 + 45t)(1+\frac{3.5}{100})^{2}

⇒ 1000 = (750 + 45t)(1.071)

⇒ t = 4.08

Hence, total time required will be 2 + 4.08 = 6.08 years.

What’s the answer? <br> Idk what it is
Aleks [24]

Answer:

B -9/7

Step-by-step explanation:

We need to find a number between

-3 1/3 < x < -4/5

We want a number smaller than between -3 1/3 and -.8

Looking at the choices

-9/7 = - (7/7 + 2/7) = -(1+2/7) = -1 2/7

That is between -3 1/3 and  -4/5
