4. Josh bought 5 pounds of peanuts for $15.55. What is the constant of proportionality that relates the cost, y, to the
number of pounds of peanuts, x?
A. $3.05
B. $10.05
C. $3.11
D. $77.75
Divide 15.55/5 and get $3.11. From there, you just mark that answer c really. For constant of proportionality just divide the cost by how much you bought (cost divided by pounds) in this case
