Respuesta :
Since the company spends 20$ on each doll and sells each for 30$ thats a 10$ profit.
If the company spends 400$ on promotion it would take 40 dolls since
400$ / 10$(amount of profit per doll) = 40
so to make the promotion back it would be 40 dolls but the question was to make PROFIT so it must be 41 dolls
Answer:
Inequality represents this problem is [tex]20x+400 < 30x[/tex] and the company must sell more than 40 dolls to make a profit.
Step-by-step explanation:
Cost of making 1 doll = $20
Let the no. of dolls be x
Cost of making x doll = $20x
Promotion of the dolls costs $400
So, Total cost price = 20x+400
The company sells each doll for $30
Selling price of x dolls = 30x
SP = 30x
CP =20x+400
For profit SP > CP
So, Equation : [tex]20x+400 < 30x[/tex]
[tex]400 < 10x[/tex]
[tex]40 < x[/tex]
So, the company must sell more than 40 dolls to make a profit.
Hence inequality represents this problem is [tex]20x+400 < 30x[/tex] and the company must sell more than 40 dolls to make a profit.
