Step-by-step explanation:
Starting Value: 24
Rate of change: -4
The equation is 24 minus t times -4, because Blake is eating 4 chocolates every night
C = 24 - 4t
Number of Days after Blake's B-day     Number of chocolates remaining
              0                        C = 24 - 4(0) = 24
              1                         C = 24 - 4(1) = 20
              2                        C = 24 - 4(2) = 16
              3                        C = 24 - 4(3) = 12
The equation is C = 24 - 4(t), where t represents the number of days after Blake's birthday.
