Question

Grapes are sold by the pound. The table shows the total cost for different weights.

Answer 1

Answer:

c = 2.46p i did the quiz

Answer 2

Answer:

Option D.

Step-by-step explanation:

Let p be the number of ponds and c be the total cost of p .

We know that cost is directly proportional to quantity.

$c\propto p$

$c=kp$       .... (1)

where, k is constant of proportionality or cost of 1 pound.

From the given table it is clear that the cost of 3 pound is $7.38.

Substitute c=7.38 and p=3 in the above equation.

$7.38=k(3)$

Divide both sides by 3.

$\frac{7.38}{3}=k$

$2.46=k$

Substitute the value of k in equation (1).

$c=2.46p$

The equation c=2.46p expresses the relationship between the number of pounds, p, and the total cost, c.

Therefore, the correct option is D.
