Is this statement true or false? And why? (Typo: It should say substitution effect)

Lisa has no outstanding debt and she currently works 1, 500 hours a year at $20 per hour. The current real rate of interest is 2% and she consumes 95% of her income and saves the remainder. If Lisa's substation effect of the real interest rate on savings is zero, an increase in the real interest rate from 2% to 5% will lead to an increase in consumption today of $42.86
