the difference from 40000 to the future value in 2020, namely 5 years later is simply the yield or interest amount.


\bf ~~~~~~ \textit{Simple Interest Earned} \\\\ I = Prt\qquad \begin{cases} I=\textit{interest earned}\\ P=\textit{original amount deposited}\dotfill & \$40000\\ r=rate\to 11\%\to \frac{11}{100}\dotfill &0.11\\ t=years\dotfill &5 \end{cases} \\\\\\ I=(40000)(0.11)(5)\implies I=22000

What is 60% of $49000?
katen-ka-za [31]

Suppose you have a Kohls coupon of $49000 and you want to know how much you will save for an item if the discount is 60 percent.

Solution:

Replacing the given values in formula (a) we have:

Amount Saved = Original Price x Discount in Percent / 100. So,

Amount Saved = 49000 x 60 / 100  

Amount Saved = 2940000 / 100  

Amount Saved = $29400 (answer).

In other words, a 60% discount for a item with original price of $49000 is equal to $29400 (Amount Saved).

Note that to find the amount saved, just multiply it by the percentage and divide by 100.

Determine the value of a + b in the system of equations below. <br><br> 5a + 4b = 22<br> 7a-b= 11
dexar [7]

Answer:

We have a + b as;

2 + 3 = 5

Step-by-step explanation:

Here, we want go get the value of a and b

from the second equation, we can get an expression for b

We have this as;

7a - b = 11

Thus,

b = 7a - 11

Now, from here, we can substitute the value of b into the first equation

We have this as;

5a + 4(7a - 11) = 22

5a + 28a -44 = 22

33a = 22 + 44

33a = 66

a = 66/33

a = 2

Recall;

b = 7a - 11

substituting the value of a from above;

b = 7(2) - 11

b = 14 - 11

b = 3
