Answer:
To make a profit of at least $500 she must sell at least 12 necklaces
Step-by-step explanation:
Joyce rented a booth at a carnival at a cost of $95 to sell handmade beaded necklaces. The cost of making and packaging each beaded necklace was $15. If Joyce sells the beaded necklaces at $35 each then we have to find beaded necklaces she sell to make a profit of at least $500.
The costs side of the equation, we have:
Let no. of necklaces that she sell are x
∴ The cost of making and packaging x beaded necklace is $15x
Total Cost = 95+15x
Now, Joyce sells the beaded necklaces at $35 each. Therefore, selling price will be $35x
To make a profit of at least $500 the equation can be written as


⇒ 
Hence, to make a profit of at least $500 she must sell at least 12 necklaces

Answer:
p = -4
Step-by-step explanation:
So first of all, you need to combine like terms. In order for that to happen, you need the like terms on one side. You get rid of a number by adding ( if subtraction), multiplying (if division), and subtracting (if addition) by its reciprical. Since it is a negative 3, you add it. Whatever you do to one side, you have to do to the other. That leaves us to 4p = 9 + 7p +3 or 4p = 12 + 7p. Since 7p is positive, you have to subtract from both side leaving us with 4p - 7p = 12 or -3p = 12. You then divide both sides with -3 to isolate the variable leaving us with p = -4
