Kelsey has to pay $200 to rent a booth at the craft fair. the materials for each pendant cost $7.80, and she plans to sell each pendant for $13.50. to make a profit, she must make more money than she spends. kelsey has already made 10 pendants.

kelsey will pay 221.3 and she has made 135 if thats what your looking for sorry if i miss understood it

Step-by-step explanation:

Let's calculate how much she will spend:

She has to pay $200 for the rent.

She made 10 pendants that costed $7.80 each, that's a total of 10*$7.80 = $78.

Therefore, she will spend $200 + $78 = $278.

Let's define x as the amount of pendants she makes.  

To make a profit, the amount of pendants she makes, multiplied by $13.50 that is the price, has to be greater than $280 added to the amount of pendants she makes, multiplied by $7.80 that is the cost.

We write that as  

13.50x > 280 + 7.80x

Let's subtract 7.80x on both sides:

13.50x -7.80x > 280 + 7.80x - 7.80x

5.70x > 280

Now we divide by 5.70 on both sides:

5.70x/5.70 > 280/5.70

x > 49.1

To make profit, she needs to make and sell more than 49 pendants.
