1) Ethan put $700 into a Certificate of Deposit (CD) account that earns 1.8% interest each year. What will the interest of the C
Inga [223]

Answer:

The interest After 6 years is $ 79.03  

Step-by-step explanation:

Given as :

The principal amount deposited in account = $ 700

The rate interest earn = 1.8 % per year

The Time period = 6 years

<u>From Compounded Method </u>

Amount = Principal × (1 +\dfrac{\textrm Rate}{100})^{\textrm Time

Or, Amount = $ 700 × (1 +\dfrac{\textrm 1.8}{100})^{\textrm 6

Or, Amount =  $ 700 × 1.018^{6}

Or, Amount =  $ 700 × 1.1129

∴ Amount = $ 779.03

Now , Interest = Amount - Principal

I.e Interest = $ 779.03 - $ 700 = $ 79.03

Hence The interest After 6 years is $ 79.03  ,  Answer

In 1975 1000 tons of coal was manufactured. It is 10% greater in 1976 and 5% less in 77. What is the final about of coal in 1977
Digiron [165]
In 1975 it was 1000tons, ok, well, in 1976 it went up by 10%, how much is a 10% increase?

\bf \begin{array}{ccllll}&#10;coal&\%\\&#10;\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\&#10;1000&100\\&#10;x&100+10&#10;\end{array}\implies \cfrac{1000}{x}=\cfrac{100}{100+10}\implies \cfrac{1000\cdot 110}{100}=x&#10;\\\\\\&#10;1100=x

well, in 1976 it was 1100 tons then, and in 1977 it went down by 5% of 1100, well, if we take 1100 to be the 100%, then what is a 5% decrease?

\bf \begin{array}{ccllll}&#10;coal&\%\\&#10;\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\&#10;1100&100\\&#10;x&100-5&#10;\end{array}\implies \cfrac{1100}{x}=\cfrac{100}{100-5}\implies \cfrac{1100\cdot 95}{100}=x
