Continue using the same environment for this question: Sheila lives for two periods. She earns $100 in the first period and $110 in the second period. She wants to consume exactly the same amount in both periods. The interest rate at which she can save and borrow is 10%. There is no inflation.

Now suppose that Sheilas first-period income goes up by 5%. What is her marginal propensity to consume? Provide your answer as a decimal number, not a percentage, and approximate it to three decimal places
