Seth is deciding whether or not he should become a member of the YMCA to use their volleyball courtsThe membership cost is $138 Members pay $7 to rent the volleyball courtsNon-members can rent the court also, but they have to pay $9 each timehow many times would Seth need to rent the court in order for it be cheaper to be a member than a non member?

Let x be the number of times Seth would need to rent the court for it to be cheaper to be a member than a non-member.

For members, the total cost would be 138 + 7x.
For non-members, the total cost would be 9x.
We can set up the inequality 138 + 7x < 9x and solve for x:
138 < 2x
69 < x
So Seth would need to rent the court at least 70 times for it to be cheaper to be a member than a non-member.

To find out how many times Seth would need to rent the court for it to be cheaper to be a member than a non-member, we can set up the following equation:

$138 + $7x < $9x

Where x represents the number of times Seth rents the court.

Let's solve the equation step-by-step:

1. Subtract $7x from both sides of the equation to isolate the variables on one side:
$138 < $9x - $7x

2. Simplify the right side:
$138 < $2x

3. Divide both sides of the equation by $2 to solve for x:
$138 / $2 < x

4. Simplify:
$69 < x

Therefore, Seth would need to rent the court more than 69 times for it to be cheaper to be a member than a non-member.

To determine how many times Seth would need to rent the court in order for it to be cheaper for him to become a member than a non-member, we need to compare the costs of being a member versus the costs of being a non-member.

Let's break it down:

- Membership cost: $138
- Cost per court rental for members: $7
- Cost per court rental for non-members: $9

First, let's calculate how many court rentals Seth would need as a member to make the membership cost worthwhile:

Membership cost ÷ Cost per court rental for members = $138 ÷ $7 = 19.71

Since you cannot have part of a rental, we will round the value up to the nearest whole number, making it 20 rentals.

Now, let's calculate the cost of 20 court rentals for non-members:

Cost per court rental for non-members × Number of rentals = $9 × 20 = $180

From the calculations, we can see that if Seth rents the court at least 20 times, it would be cheaper for him to become a member rather than paying as a non-member.

So, Seth would need to rent the court at least 20 times for it to be cheaper to become a member than a non-member.
