Answer:
Additional <em>26</em> pendants are to be sold to make profit.
Step-by-step explanation:
Rent of booth at the craft fair = $200
Cost of material for each pendant = $7.80
Let Kelsey makes number of pendants.
To calculate the total spending, we have to add the rent of booth at the craft fair and cost of material for number of pendants.
Cost of material for number of pendants = Cost of material for each pendant multiplied by number of pendants
Cost of material for number of pendants = $7.80
So, total cost = $200 + $7.80
Now, each pendant is sold at $13.50
So, total money made by selling pendants = $13.50
For making profit, total money made must be greater than the total cost.
Therefore, the inequality becomes:
Let us solve the inequality now:
So, at least 36 pendants are to be sold to make a profit.
Additional 36-10 = <em>26</em> pendants are to be sold to make profit.
