13. n + (n+1) + (n+2) = 51, 3n + 3 = 51, n = 48/3 = 16, so integers are 16,17,18.

14. n + (n+1), + (n +2) = -15, 3n + 3 = -15, n = -18/3=-6, so integers are -6,-5,-4

15. n + (n+1) + (n+2) + (n+3) = 30, 4n + 6 = 30, n = 24/4 = 6, so integers are 6,7,8,9.

16. 5x + 4(x+3) = 66, 9x + 12 = 66, x = 44/9 = $4.89/hour.
