Answer:
1/3
Step-by-step explanation:
A direct variation has the form y=kx
k is the constant of proportionality
y = 1/3x
The constant of proportionality is 1/3
Y = mx + c therefore
m = 1
c = -2
Each can of green beans costs ($3.00/5) = 60¢ at the
village market, and ($6.10/10) = 61¢ at Sam's Club.
If you're watching every penny, then that MIGHT be enough
of a difference to make you decide to buy your beans at the
village market, but not necessarily.
If, say, the village market is farther away from you, or if there are
other things you're going to get from Sam's anyway, then you
should buy your beans there too.
