The 3 in the linear function f(w) = 2.5w + 3 represents "the amount of rainfall at week 0". option A.
The number of books per month eric donated on average between months 3 and 8 is 11 books per month. Option C.
What does 3 represents in the linear function?
f(w) = 2.5w + 3
At week 0, w = 0
f(w) = 2.5w + 3
f(0) = 2.5(0) + 3
f(0) = 0 + 3
f(0) = 3
After 3 months, 157 books left
After 8 months, 102 books left
Number of books per month eric donated on average between months 3 and 8 = Change in books left / Change in months
= (102 - 157) / (8 - 3)
= -55/5
= 11
Hence, 11 books are donated per month between months 3 and 8.
