Mariya was asked to solve StartFraction a over negative 13 EndFraction less-than-or-equal-to negative 16 and then graph the solution. Her work is shown below. Step
Mariya’s work

StartFraction a over negative 13 EndFraction less-than-or-equal-to negative 16

Step 1

(Negative 13) StartFraction a over negative 13 EndFraction less-than-or-equal-to negative 16 (negative 13)

Step 2

a greater-than-or-equal-to 208

Step 3
A number line going from 205 to 211. An open circle is at 208. Everything to the right of the circle is shaded.

In which step, if any, did Mariya make a mistake in her work?

Step Mariya’s work StartFraction a over negative 13 EndFraction less-than-or-equal-to negative 16 Step 1 (Negative 13) StartFraction a over negative 13 EndFraction less-than-or-equal-to negative 16 (negative 13) Step 2 a greater-than-or-equal-to 208 Step 3 A number line going from 205 to 211. An open circle is at 208. Everything to the right of the circle is shaded. In which step, if any, did Mariya make a mistake in her work?

Step 3  because the circle on the number line is open.
