See a solution process below:

Explanation:

Subtract #color(red)(3.9)# from each side of the inequality to solve for #c# while keeping the inequality balanced:

#7.4 - color(red)(3.9) >= c + 3.9 - color(red)(3.9)#

#3.5 >= c + 0#

#3.5 >= c#

To state the solution in terms of #c# reverse or "flip" the entire inequality:

#c <= 3.5#
