Atoy company spends $20 for every doll it makes. promotion of the dolls costs $400 and the company sells each doll for $30. how many dolls must the company sell to make a profit? what inequality represents this problem?

Inequality represents this problem is   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 :

So,  the company must sell more than 40 dolls to make a profit.

Hence inequality represents this problem is   and the company must sell more than 40 dolls to make a profit.
