Answer:
8 hours.
Explanation:
An Equation can be created:
y = 38 + 6.30t ("t" denotes time taken in hours and "y" amount cost)
============
Solve for t, given amount cost: $88.40
38 + 6.30t = 88.40
6.30t = 88.40 - 38
6.30t = 50.4
t = 50.4/6.3
t = 8
So, they can use the meeting room for 8 hours.
- Rate of pay=$6.3/h
The equation is
- y=38+6.3t
So
- 38+6.3t=88.4
- 6.3t=88.4-38
- 6.3t=50.4
- t=8
FOR 8 HOURS
