Answer:
$1006.20
Step-by-step explanation:
This is an example of compound interest.
To work this out you would first have to convert the percentage into a decimal, you can do this by dividing 3 by 100, which gives you 0.03. You are dividing by 100 as percentages are out of 100. Then you would add 1 to 0.03, which gives you 1.03. This is because you are finding percentage increases. Then you would multiply 894 by 1.03 to the power of 4, which gives you 1006.20. This is because you are finding 3 percent and adding it on and then finding 3 percent of that, this is why we put it to the power of how much time.
1) Divide 3 by 100.
2) Add 1 to 0.03.
3) Multiply 894 by 1.03 to the power of 4.
The first step for solving this expression is to insert what a and b stand for into the expression. This will change the expression to the following:
2(2)(4)³ + 6(2)³ - 4(2)(4)²
Now we can start solving this by factoring the expression
2(2 × 4³ + 3 × 2³ - 4 × 4²)
Write 4³ in exponential form with a base of 2.
2(2 ×
+ 3 × 2³ - 4 × 4²)
Calculate the product of -4 × 4².
2(2 × + 3 × 2³ -4³)
Now write 4³ in exponential form with a base of 2.
2(2 × + 3 × 2³ -)
Collect the like terms with a base of 2.
2( + 3 × 2³)
Evaluate the power of 2³.
2( + 3 × 8)
Evaluate the power of.
2(64 + 3 × 8)
Multiply the numbers.
2(64 + 24)
Add the numbers in the parenthesis.
2 × 88
Multiply the numbers together to find your final answer.
176
This means that the correct answer to your question is option A.
