Answer:
x = 22.5
Step-by-step explanation:
![\frac{BH}{DH} = \frac{HM}{HT} \\ \frac{6}{15 + 6} = \frac{9}{9 + x} \\ \frac{6}{21} = \frac{9}{9 + x} \\ 6(9 + x) = 9 \times 21 \\ 54 + 6x = 189 \\ 6x = 189 - 54 \\ 6x = 135 \\ x = \frac{135}{6} \\ x = 22.5](https://tex.z-dn.net/?f=%20%5Cfrac%7BBH%7D%7BDH%7D%20%20%3D%20%20%5Cfrac%7BHM%7D%7BHT%7D%20%20%5C%5C%20%20%5Cfrac%7B6%7D%7B15%20%2B%206%7D%20%20%3D%20%20%5Cfrac%7B9%7D%7B9%20%2B%20x%7D%20%20%5C%5C%20%20%5Cfrac%7B6%7D%7B21%7D%20%20%3D%20%20%5Cfrac%7B9%7D%7B9%20%2B%20x%7D%20%20%5C%5C%206%289%20%2B%20x%29%20%3D%209%20%5Ctimes%2021%20%5C%5C%2054%20%2B%206x%20%3D%20189%20%5C%5C%206x%20%3D%20189%20-%2054%20%5C%5C%20%206x%20%3D%20135%20%5C%5C%20x%20%3D%20%20%5Cfrac%7B135%7D%7B6%7D%20%20%5C%5C%20x%20%3D%2022.5)
3×2=6+4=d the 3×2 is how much the cost is and 6+4 is 10 so she paid 10 dollars
