Answer:
Equation : 35 + 6.40t < 86.20
t = less than 8 hours
Explanation:
If t equals the number of hours they can rent the room before going over their set limit, we would add the base amount (35) to the hourly (6.40t) less than 86.20.
So :
35 + 6.40t < 86.20
6.40t < 51.20 (subtract 35 on both sides)
t < 8 (divide 6.40 on both sides)
