Evaluate the numerical expression. −8.5(9.4 − 6.1) a) −13.50 b) −28.05 c) −86 d) 3.5

To evaluate this expression, we must keep in mind the order of operations. This order is outlined by PEMDAS, which tells us that we should compute operations in parentheses first, exponents next, then multiplication and division, and finally addition and subtraction. Using this knowledge, we should simplify what is in parentheses first in our expression, as shown below:

−8.5(9.4 − 6.1)

-8.5(3.3)

Now, we can perform the final operation, which is multiplication. Keep in mind that our answer should be negative because we are multiplying one negative number by one positive number!

-28.05

Therefore, your answer is -28.05, or answer choice B.

Hope this helps!

the answer is b.)
