Answer:
$12.
Step-by-step explanation:
1) if price of one doll is 'x', of one dress is 'y', then the condition 'buys one doll and one dress, it will cost her $21.00' can be written as x+y=21;
2) the condition 'buys two dolls and three dresses, it will cost her $51.00' can be written as 2x+3y=51;
3) it is possible to make up the system:
![\left \{ {{x+y=21} \atop {2x+3y=51}} \right. \ = > \ \left \{ {{x=12} \atop {y=9}} \right.](https://tex.z-dn.net/?f=%5Cleft%20%5C%7B%20%7B%7Bx%2By%3D21%7D%20%5Catop%20%7B2x%2B3y%3D51%7D%7D%20%5Cright.%20%5C%20%3D%20%3E%20%5C%20%5Cleft%20%5C%7B%20%7B%7Bx%3D12%7D%20%5Catop%20%7By%3D9%7D%7D%20%5Cright.)
4) the price of one doll is 12$.
