Tereka and Emma each deposit money in savings accounts. The amount of money, in dollars, in Tereka’s account after x years is mo

deled by the function T(x) = 472(1.04)x. The amount of money, in dollars, in Emma’s account after x years is modeled by the function E(x) = 485(1.09)x. What is the difference between the initial amounts Tereka and Emma deposit?

Given:

Amount of money in Tereka’s account : T(x)=472(1.04)^x

Amount of money in Emma’s account : E(x)=485(1.09)^x

To find:

The difference between initial amounts Tereka and Emma deposit.

Solution:

Substitute x=0 in the given functions, to get the initial amount of money they deposit.

T(0)=472(1.04)^0

T(0)=472(1)

T(0)=472

So, the initial amount Tereka deposit is $472.

E(0)=485(1.09)^0

E(0)=485(1)

E(0)=485

So, the initial amount Emma deposit is $485.

Difference between the initial amounts Tereka and Emma deposit is

485-472=13

Therefore, the difference between initial amounts Tereka and Emma deposit is $13. Emma deposit $13 more than Tereka.

2. Tom bought 500 shares of a company’s stock for $11.06/share. He pays a broker a commission of $12 to buy and sell stock. Afte
goldfiish [28.3K]

Step-by-step explanation:

a.)Buying: total cost

Total cost= commission + (price per share× Number of of shares ) ;

Total cost= 10 + (11.06×500)=$5540

b.)Net gain or loss;

First, find cash received from sale of stock and deduct commission;

Cash from sale =10×500= $ 5000

deduct commission= 5000-10= $4990

Gain or loss= sale-cost = 4990-5540 = -$550, meaning there is a loss.

c.) Annual rate of return= (net gain or loss/amount paid)×100%

return= -550/(5540)×100 = -9.92%
