Nat opened an account that earns 1.4% simple annual interest. He will earn $21 total interest after 3 years. How much did he dep

nataly862011 [7]

Answer:

Therefore Nat deposited $500 when he opened the account.

Step-by-step explanation:

Given that Nat opened an account that earns 1.4% simple annual interest. He will earn $21 total interest after t years.

The simple interest formula is

$I= Prt$

I= interest= $21

P= Principal=?

t= time in year= 3 years.

r = rate of interest= 1.4%= 0.014

$I= Prt$

$\Rightarrow P=\frac{I}{rt}$

$=\frac{21}{0.014\times 3}$

=$500

Therefore Nat deposited $500 when he opened the account.

snow_tiger [21]

$\bf \qquad \textit{Simple Interest Earned}\\\\
I = Prt\qquad 
\begin{cases}
I=\textit{interest earned}\\
P=\textit{original amount deposited}\to& \$2300\\
r=rate\to 20\%\to \frac{20}{100}\to &0.20\\
t=years\to \frac{27}{12}\to &\frac{9}{4}
\end{cases}
\\\\\\
I=2300\cdot 0.2\cdot \cfrac{9}{4}$

The sum of two numbers is 79. Three

Semmy [17]

Answer:

The two numbers are 23 and 56

Step-by-step explanation:

Let's say the two numbers are A and B.

We are told:

1) A+B=79

2) 3A+5B=283

Let's take the first expression and solve for A:

A+B=79

A=79-B

Now use this value of A in the second expression:

3A+5B=283

3(79-B)+5B=283

237-3B+5B=283

2B = 46

B = 23

Since B=23, we know from 1) that

A+B=79

A+23=79

A = 56

CHECK:

Does A+B=79?

56+23 = 79? YES

Does 3A+5B=283?

3(56)+5(23)=283

168 + 115 = 283? YES
