A toy company spends $20 for every doll it makes. Promotion of the dolls costs $400 and the company sells each doll for $30. How
Romashka-Z-Leto [24]

Answer:

20d+400< 30d

Step-by-step explanation:

we know that

The profit is equal to the number of dolls multiplied by the selling price minus  the number of dolls multiplied by the cost of each doll minus the cost of the promotion of the dolls

To make a profit, the number of dolls multiplied by the selling price minus  the number of dolls multiplied by the cost of each doll must be greater than the cost of the promotion of the dolls

Let

d -----> the number of dolls

The linear inequality that represent this problem is

30d-20d > 400

Adds 20d both sides

30d > 20d+400

Rewrite

20d+400< 30d
