The business rule from Section 4.1 on p. 23 is as follows: "A user selects a number of items to buy. The total price is accumulated for those items." Color in Figure 4.9 according to this rule, based on the traffic light colors in Section 3.2 on p. 14. Do so as it would be reported by Fit, according to whether the tests pass. You don't need to bother to insert actual values where a test value is wrong.
