The term that completes the blank and fits the description is an array
<h3>How to complete the blank?</h3>
From the question, we understand that:
- The variable term holds multiple values
- It uses square brackets
- it is defined by a single variable
The term that fits the above highlights is array
Hence, the complete statement is:
<em>array can hold multiple values within a single variable and is defined by having values between square brackets.</em>

We know for the problem that the performer earned $120 at a performance where 8 people attend. We also know that he u<span>ses 43% of the money earned to pay the costs involved in putting on each performance, so we need to find the 43% of $120. To do that, we are going to divide 43% by 100%, and then multiply it by $120:
</span>
Now we know that the performer uses $51.6 of $120 to pay the costs involved in putting on each performance. The only thing left to find his profits is subtract $51.6 from $120:
We can conclude that the performer makes a profit of $68.4 when 8 people attend his performance.
D is the answer. Hope this helped.
