Answer:
A. 13 people
Explanation:
The equation is 13x + 149.50 ≤ 323
Step 1: Subtract 149.50 from both sides.
13x + 149.5 − 149.5 ≤ 323 − 149.5
13x ≤ 173.5
Step 2: Divide both sides by 13
13x/13 ≤ 173.5/13
x<13.346154
Since you cant have 13.34 of a person you have to round to 13
So, the greatest number of people Justin can allow to attend the workshop is 13 people
