Mr. Bird has $100 income this year and zero income next year. The market interest rate is 10

percent per year. Mr. Bird also has an investment opportunity in which he can invest $50 today and

receive $80 next year. Suppose Mr. Bird consumes $30 this year and invests in the project. What

will be his consumption next year? (We assume that he will consume all of his wealth in the next

year.)
