For this case we have the following solution.
x = gallons of water to be added
For the 10% solution we have:
0.1 * 8 = 0.8
Then, for 5% we have:
(0.8 / x + 8) = 0.05
Rewriting:
(0.8 / x + 8) = (5/100)
Answer:
An equation can be used to find x, the humber of gallons of water he should add is:
(0.8 / x + 8) = (5/100)
Answer:
$210
Step-by-step explanation:
We will model the food booth and game booth as linear functions 
where 
is the charge per day, 
is the flat fee, and 
is the number of days.
Food booth: 
Game booth: 
We solve for both equations, letting 
:
We add the two values to obtain the total cost of $210.
