Let
t--------> the amount Thomas earned in dollars
we know that
Thomas earned [tex]\$49[/tex] or more
so
[tex]t\geq \$49[/tex]
The solution of the inequality is the interval------------> [49,∞)
see the attached figure to better understand the problem
The solution is the shaded area
therefore
the answer is the option
[tex]t\geq \$49[/tex]
