In order to solve the given equation, we simply must apply the rules of PEMDAS, which means that we need to start with the parenthesis, exponent, multiplication, division, addition, and lastly subtraction.

In our case, we'll start by equating the values inside the parenthesis.

= 4 [ 2.5 + 3(20 + 7)]

= 4 [ 2.5 + 3(27)]

=4 [ 83.5 ]

= 334

Final answer:
