Answer:
The maximum amount of money the chemistry club can spend without going over their buget is $81.4 ... With a total of 6 hours their allowed to use the room for.
Step-by-step explanation:
$49 is our constant and will not change. 5.40 however will. Let's use variable h for the amount hours they can rent the room for. Now we can make an inequality; 
49+ 5.40h < 86.80
5.40h < 86.80
5.4h< 37.8
h< 7
Now that we know h will have to be less than seven for the chemistry club to spend less than their buget we can find that 6 is the maxium amount of hours they can spend in the room while staying within their budget.

I would say 32 <span>• 3/4 or 32* 3/4 
</span>
        
             
        
        
        
Well let’s make it a decimal. 
.75 = .84 + Y
So if .84 is more than .75 then subtract 
.75 from .84 and you have your answer then convert to fraction
