Sam can type 365 words in 8 minutes. What is the constant of proportionality that relates the number of words typed, y, to the number of minutes it took to type, x? (Remember that constant of proportionality is k = y/x) (1 point)
A. 50 words per minute
B. 46 words per minute
C. 44 words per minute
D. 36 words per minute
To find the constant of proportionality, we divide the number of words typed (365) by the number of minutes it took to type (8):
k = 365/8
Simplifying the expression:
k ≈ 45.625
Rounding to the nearest whole number:
k ≈ 46
Therefore, the constant of proportionality is 46 words per minute. The answer is option B.
