A population consists of 100 individuals, randomly numbered from 0 to 99. They are evenly divided into 10 groups in ascending order, with respective group numbers 1 to 10. A systematic sampling method is used to select a sample of size 10. According to the rule, if the number t is chosen from the first group, then the number chosen from the k-th group should have the same unit digit as the unit digit of t + k. If t = 7, determine the number that should be selected from the 8th group.
