Answer:
WACC= 17.95%
Explanation:
Weighted average cost of capital is the average cost of all of the long-term types of finance used by a company weighted according to the that amount of finance used in relation to the total pool of fund.
It is calculated using the formula below:
WACC = (We×Ke)  +  (Wd×Kd)
Ke-cost of equity- 22%
We- equity weight- 100% - 45% = 55%
Kd-After tax cost of debt-10.3%
Wd- 45%
After tax cost of debt = Before tax ×× (1- tax rate)
After tax cost of debt = 13%× (1-0.21) = 10.3%
Cost of equity = 22%
WACC =(0.55× 22%) + (0.45× 13%)=17.95%
WACC= 17.95%

The correct answer to this open question is the following.
Although there is no further information about the case of study, we can say that the question possible refers to the case where the name of the company is just "The Client." The name of the document is "Leading Innovation Change - The Kotter Way."  
This case refers to the challenges faced by an organization when it is time to innovate. Many members want to innovate but the culture of the company or the lack of proper leadership from managers often hinders the innovation efforts of the company. 
So some of the elements of Kotter's Eight Stages of Leading Change that were included in the case were the following.
Create Urgency. The creation of new products of the company was limited and was not enough to compete in the future. A sense of urgency was needed to implement innovation. 
Form a Powerful coalition. The company had to be very selective about the kinds of products that could help it to successfully compete in the future. The company had to use the best it had to establish priorities. 
Create a vision for change. It was critical for the company to establish a new vision to get the results it needed. A renovation of the processes to face new necessities was imperative. Change has to be part of every member's mind. 
Communicate the vision. This new vision had to be shared through the entire company. The members had to understand the importance of the innovative practices and each and every one of them had to be part of this new mentality.
