Question 1154986: Can somebody please help me? Michael records the number of stamps in his stamp collection each month. At the end of week 1 he has 21 stamps. Here are the monthly totals that Michael has recorded so far: 21, 29, 37, 45, and 53. Which of the equations below best represents Michael's total number of stamps (S) as a function of the number of months (m)?
S(m) = 21m
S(m) = m + 21
S(m) = 8m + 13
S(m) = 8m + 21

Hi
month totals increase ... by 8 | recorded: 21, 29, 37, 45, and 53
slope is 8
S(m) = 8m + b
FIRST MONTH... S(1)= 8*1 + b
21 = 8 + b
13 = b
S(m) = 8m + 13 |(S) as a function of the number of months (m)
Check Your answer using any of the monthly totals given:
s(4) = 45 as one example
