we have
[tex]2.9(x+8)< 26.1[/tex]
Solve the inequality
[tex]2.9(x+8)< 26.1[/tex]
Divide both sides by [tex]2.9[/tex]
[tex](x+8)< (26.1/2.9)[/tex]
[tex](x+8)< 9[/tex]
Subtract [tex]8[/tex] from both sides
[tex]x< 9-8[/tex]
[tex]x< 1[/tex]
the solution is the interval --------> (-∞,1)
therefore
the answer is
The solution in the attached figure
