The table shows the proportional relationship of the cost of lettuce per pound.
Pounds of Lettuce Price
0 $0.00
2 $2.02
4 $4.04
6 $6.06
10 $10.10
What is the constant of proportionality in terms of the number of dollars per pound of lettuce?
A.
0.505
B.
2.02
C.
1.01
D.
3.02
C. 1.01
To find the constant of proportionality, we need to take the price and divide it by the number of pounds of lettuce.
For example, taking the first set of data:
Price: $2.02
Pounds of lettuce: 2
Constant of proportionality = $2.02 / 2 = $1.01
This applies to all the other sets of data as well.
