At the deli counter in the supermarket, Nigel paid $10
for 212
pounds of roast beef. The cost of deli meat is proportional to its weight. What is the equation for the graph of this proportional relationship?
x=_y
x = weight of roast beef in pounds
y = cost of roast beef
The equation for the graph of this proportional relationship is:
y = kx
Where k is the constant of proportionality.
