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. Part C
It takes Kelsey 5 hours to make 12 pendants. If she works 8 hours per day for 3 days before the craft fair, can she make enough additional pendants to sell so that she can make a profit of at least $50? Explain.

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.

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.

step-by-step explanation: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
