At the beginning of the year, Mr. L put $50,000 cash into Investment X. At the end of the year, he received a check for $2,800, representing his annual return on the investment. Mr. Ls marginal tax rate on ordinary income is 39.6 percent. However, his return on Investment X is a capital gain taxed at 20 percent. At the beginning of the year, Mr. L could have invested his $50,000 in Business Z with an 8 percent annual return. However, this return would have been ordinary income rather than capital gain.

1. Considering the fact that Mr. L could have invested in Business Z, how much implicit tax did he pay with respect to Investment X?

2. Did Mr. L make the correct decision by putting his $50,000 into Investment X instead of Business Z?
