1a You now need to calculate the cost of debt for Tesla. Consider the following four bonds issued by Tesla: What is the weighted average cost of debt for Tesla using the book value weights and the market value weights? Does it make a difference in this case if you use book value weights or market value weights? 04/20/2020

Why is my book value weights and market value weights percentage the same amount but the total is different? Did I input the formula wrong? Please help

	Book Value	Book Value Weight	Yield to Maturity	Weighted Average Cost
1	1,200,000	32.88%	-70.183	-23.07386301
2	850,000	23.29%	-39.192	-9.12690411
3	1,600,000	43.84%	-20.192	-8.851287671
Total	3,650,000
Weighted Average Cost of Debt (Book Value)
	Market Value	Market Value Weight	Yield to Maturity	Weighted Average Cost
1	1,380,000	32.88%	-70.183
2	977,500	23.29%	-39.192
3	1,840,000	43.84%	-20.192
Total	4,197,500

Am I doing the formula wrong because I'm getting the same market and book value?
