Gareth has $2,000 to invest. Putting the money in a savings account at his local bank will earn him 2.2% annual interest and giv

Alenkinab [10]

Answer:

Option c. 18 withdrawals is correct

Step-by-step explanation:

Gareth has to invest = $2,000

His local bank gives 2.2% annual interest and gives him the ability to make ATM withdrawals without any charges.

In an online savings gives 4.85% annual interest, but charges $3 every time he makes an ATM withdrawal.

Let us find the amount of interest earned from the local bank.

The amount of interest earned from Local Bank = 2.2% of 2000

= $\frac{22}{100}$ × 2000

= 0.022 × 2000 = $44

The amount of interest earned from online savings = 4.85% of 2000

= $\frac{4.85}{100}$ × 2000

= 0.0485 × 2000 = $97

As it is given that savings account has no ATM withdrawal charges but online savings account charge $3.00 per withdrawal.

so we need to make x withdrawals from both accounts such that:

97 - 3x = 44

Let us solve for x.

Upon subtracting 97 from both sides of or equation we will get,

97 - 97 - 3x = 44 - 97

3x = -53

$\frac{3x}{-3}=\frac{-53}{-3}$

x = 17.666 rounded to 18

Therefore, Gareth must make 18 ATM withdrawals every year for the local savings account to be a better deal than the online savings account.

For a particular clothing store, a marketing firm finds that 16% of $10-off coupons delivered by mail are redeemed. Suppose six

stich3 [128]

Answer:

The expected number of coupon is $E(X) = 1.6$

Step-by-step explanation:

From the question we are told that

The probability that a $10 coupons delivered by mail will be redeemed is p = 0.16

The sample size is n = 10

Generally the expected number of coupons that will be redeemed is mathematically represented as

$E(X) = np$

=> $E(X) = 10 * 0.16$

=> $E(X) = 1.6$

Nico makes annual end-of-year payments of $5,043.71 on a four-year loan with an interest rate of 13 percent. The original princi

natita [175]

We need to find the principal amount on an interest rate of 13% where the end of year payment is $5043.71.

The original amount is $\$15002.37$ .

i = Interest rate = 13%

n = Compounding period = 4 years

E = End of year payment = $5043.71

The required formula is

$P=\dfrac{E[1-(1+i)^{-n}]}{i}\\\Rightarrow P=\dfrac{5043.71[1-(1+0.13)^{-4}]}{0.13}\\\Rightarrow P=\$15002.37$

The original principal amount was $\$15002.37$ .
