Answer:
$4
Step-by-step explanation:
30+20=50
50-48=2
2+20+=22
22-18=4
if she has 30 then gets 20 she has 50. Then she spends 48 dollars leaving her with only 2 dollars. She then makes another 20 dollars so she now has 22 dollars. She spends 18 dollars leaving her with 4 dollars.
The final amount if $10 000 invested for 6 years at 4% compounded quarterly is $12,697
<h3>Compound interest</h3>
The formula for calculating the compound interest is given as:
A = P(1+r/n)^nt
Given the following parameters
A = 10000(1+0.04/4)^4(6)
A = 10000(1+0.01)^24
A = 10000(1.01)^24
A = 1.2697(10,000)
A = $12,697
Hence the final amount if $10 000 invested for 6 years at 4% compounded quarterly is $12,697

Answer:

Step-by-step explanation:
To solve, we need to take square root of both sides first:

Now we use the property of radical shown below to simplify square root of 28:
Property: 
Now, we have:

Now we take 4 to the other side and isolate x:

first answer choice is right.
