Suppose Hans is planning to join a fitness club. Membership in the club will allow Hans to exercise for half price. Normally the exercise cost is $10. If Hans has an income of $200, the club membership fee is $50 (assume that we plot the number of exercises on the horizontal axis and a "composite good" which has a price of $1 on the vertical axis)

What is the slope of Hans's budget line before joining the club?
