To write an equation and simplify it, I'll start with this:
$4,500 = $90 + $39X Let X represent the amount of people attending the party.
Subtract 90 and both sides of the equation to make the $39X alone.
$4,410 = $39X
Divide $39 into both sides of the equation to isolate or bring X alone.
113.076923 = X
Now since we have to round down, we will do 113.
Answer: 113 people can attend the anniversary party.
The mechanical advantage of the pulley is 1.
<h2>Mechanical advantage</h2>
The ratio of the force produced by a machine to the force applied to it.
<h3>The formula for mechanical advantage.</h3>
Here, is output force and input force.
<h3>Given</h3>
A pulley is given.
<h3>To find </h3>
The mechanical advantage of the pulley.
<h3>How to find a mechanical advantage?</h3>
We know by Newton's first law.
P = W
where P is applied force
and W is the weight of the object.
Then
The mechanical advantage of the pulley is 1.
