She saved 20%.

The price of the table was 250 and she bought it for 200, meaning 1/5 of the original price was marked off. 1/5 = 20% which means it was 20% off the original price.

4. If your company purchases an annuity that will pay $50,000/year for 10 years at a 11% discount rate, what is the value of the
julsineya [31]

Answer:

The value of the annuity is $326,852.3766.

Step-by-step explanation:

Here is the required formula to find the present value of annuity:

We can find the present value of annuity:

PV = P + P (\frac{1-(1+r)^{-(n-1)} }{r})

Here:

            P = $50,000

            n = represents the number of number of periods

            r = 0.11

PV = 50,000 + 50,5000 (\frac{1-(1+0.11)^{-(10-1)} }{0.11})

PV = $326,852.3766

The value of the annuity is $326,852.3766 i.e. PV = $326,852.3766.

C. Make n subject of the formula<br>S= n/2 [2a + (n - 1)d]<br><br>please provide your working out ​
yKpoI14uk [10]

Answer:

n=\frac{4as -2ds}{(1-2ds)}

Step-by-step explanation:

S= \frac{n}{2 [2a + (n - 1)d]}

Simplifying the fraction by multiplying d into the (n-1) term,

s=\frac{n}{2 [2a + (n - 1)d] } = \frac{n}{2[2a + dn - d] }

Simplifying the fraction by multiplying 2 throughout,

s= \frac{n}{4a + 2dn-2d}

Multiply (4a + 2dn-2d) on both sides

(4a + 2dn-2d)s= \frac{n}{4a + 2dn-2d} (4a + 2dn-2d)

Cancel the (4a + 2dn-2d) on the right hand side

(4a + 2dn-2d)s= n

Multiply s to the terms,

4as + 2dns-2ds= n

Move 2dns to the right hand side by subtracting 2dns on both sides4as + 2dns-2ds-2dns= n-2dns

4as -2ds= n-2dns

On the right hand side of the equation, take out n

4as -2ds= n(1-2ds)

Divide Left hand side by (1-2ds),

n=\frac{4as -2ds}{(1-2ds)}
