Answer:

<h2>8(15-m)</h2>

Step-by-step explanation:

In the table, <em>x </em> represents the total time students take to respond free-response question. So, the replacement of the variable must be the product between the number of free-response questions and the time per questions students take.

Number of free-response questions: 15-m

Time per Item (minutes): 8

Therefore the product would be: 8(15-m), which is the expression that must replace <em>x.</em>
