Question

What is the simplified value of the expression below?

8.2 +4.1 (6.3-4)

A 9.43

B 17.63

C 28.29

D 73.49

Answer 1

The answer is B. "17.63."

Following the steps of pemdas, you would solve what's in the parentheses first.

8.2+4.1(6.3-4)

After that, multiply.

8.2+4.1(2.3)

Then complete the addition.

8.2+9.43

17.63

Answer 2

Use PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction). Solve the problem in that order.

In this case, you would first solve the parentheses (6.3-4) to get 2.3. The problem is now 8.2+4.1(2.3). Next, multiply 4.1*2.3 to get 9.43. The problem is now 8.2+9.43. After adding, the only thing that remains is 17.63.

So, the answer is B 17.63.

Hope this helps! :)
