Step-by-step explanation:
variable is n
operation is addition
constant is 2.35

The graph in the attached figure
Step-by-step explanation:
we have

Solve for x


The solution is the interval ------> (4,∞)
All real numbers greater than 4
In a number line, the solution is the shaded area at right of x=4 (open circle, the number 4 is not included in the solution)
