<span>n >= 1125
First, make an equation to express the money raised after expenses.
55n - 15n + 10000 = m
The above expression can be read as "55 dollars per running is raised, but 15 dollars is spent per running to support them. Plus we get 10000 as a constant regardless of how many runner we have." Now convert that to an inequality for at least 55000 to be raised.
55n - 15n + 10000 >= 55000
Now solve for n
55n - 15n + 10000 >= 55000
40n + 10000 >= 55000
40n >= 45000
n >= 1125
So there needs to be at least 1125 runners in order to meet the goal of $55,000.</span>
Answer:
<h3>X=-1/5=-0.2</h3>
Step-by-step explanation:
Isolate x on one side of the equation.
15x+5=2
15x+5-5=2-5 (First, subtract by 5 from both sides.)
2-5 (Solve.)
2-5=-3
15x=-3
15x/15=-3/15 (Then, divide by 15 from both sides.)
-3/15 (Solve.)
-3/15=-1/5
-1/5=-0.2
x=-1/5=-0.2
The final answer is x=-1/5=-0.2.
