Suppose a deposit of $ 2 , 000 in a savings account that paid an annual interest rate r (compounded yearly) is worth $ 2 , 209 a

arsen [322]

Answer:

5.1% (nearest tenth)

Step-by-step explanation:

Annual Compound Interest Formula

$\large \text{$ \sf A=P\left(1+r\right)^{t} $}$

where:

A = final amount
P = principal amount
r = interest rate (in decimal form)
t = time (in years)

Given:

A = $2,209
P = $2,000
t = 2 years

Substitute the given values into the formula and solve for r:

$\implies \sf 2209=2000\left(1+r\right)^{2}$

$\implies \sf \dfrac{2209}{2000}=(1+r)^2$

$\implies \sf 1.1045=(1+r)^2$

$\implies \sf \sqrt{1.1045}=1+r$

$\implies \sf r = \sqrt{1.1045}-1$

$\implies \sf r = 0.05095194942...$

$\implies \sf r = 5.095194942...\%$

Therefore, the annual interest rate is 5.1% (nearest tenth)

The manufacturing cost of a cell phone was $136. Sellers first marked up the cost by 25 percent. Sales were poor, so sellers dec

neonofarm [45]

Answer: Old selling price is $170 and new selling price is $159.12

Step-by-step explanation:

Given Cost Price , CP=$136

For old selling price

Selling Price(SP) = Cost Price(CP) + Markup Value(MV)

Now MV= $MV=\frac{CP\times 25}{100}=\$ \frac{136\times 25}{100}=\$ 34$

=>SP = $136+$34=$170

Thus old selling price is $170

For new selling price

New Markup Value(NMV) = $\frac{CP\times 17}{100}=\$ \frac{136\times 17}{100}=\$ 23.12$

=>New Selling Price , NSP= $136+$23.12=$159.12

Thus new selling price is $159.12

50 Points !!!!! What is the best estimation of the equation 7/8 − 6/11 ? Ps it is Fractions :DDD

Svet_ta [14]

Answer:

Gross estimate: 1/2

Good estimate: 1/3

Exact answer: 29/88

Step-by-step explanation:

You ask for an estimate.

7/8 is close to 1

6/11 is close to 1/2

1-1/2 = 1/2

This is a gross estimate.

The exact answer is found by getting a common denominator of 88

7/8 *11/11= 77/88

6/11*8/8 = 48/88

77/88 -48/88 =29/88

This is just a little less than 1/3

Rounding our answer 29 is close to 30 and 88 is close to 90

30/90 = 1/3
