We are given the following expression:


c-20+(4c)

we are asked to determine the value of the expression when c = 30. To that, we replace the value of c in the expression for 30, like this:


30-20+(4*30)

Now we solve the operation in the parenthesis:


30-20+120

Now we solve the subtraction:


10+120

Now we solve the last operation:


130

Therefore, the value of the expression when c = 30 is 130
