Answer:

  • B) 7.25

Step-by-step explanation:

Proportional relationship equation:

  • y = kx, where k-constant of proportionality

In the given table, number of buckets represent input values (x) and the price represents output values (y).

We have for the first column:

  • x = 2, y = 14.50

Find the value of k by plugging in the values of x and y:

  • 14.50 = 2k
  • k = 14.50/2
  • k = 7.25

Same result will be obtained with the other columns, therefore the constant of proportionality is 7.25.

Answer:

b) 7.25

Step-by-step explanation:

Formula we use,

→ y = kx

→ k = y/x

Now the value of k will be,

→ k = y/x || → k = y/x

→ k = 14.5/2 || → k = 36.25/5

→ [ k = 7.25 ] || → [ k = 7.25 ]

Hence, the answer is 7.25.
