Therefore x = -8.
Answer:
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
Adds 20d both sides
Rewrite
D because it shows the . of each percentage
