vivado [14]

Answer:

b. 3t ≥ 36

Step-by-step explanation:

She gets $3 per three-pointer. The variable <em>t</em> stands for three-pointer. So in mathematical terms, it would be 3<em>t</em>.

She wants a minimum of 36 dollars, therefore the sign would be ≥. This means 3<em>t </em>has to be greater than or equal to 36.

So, 3<em>t</em> ≥ 36
