Each pound of potatoes costs $1 20 The total cost, in dollars, is given by the function c(p) = 1.2p.

Pound 1. 2. 3. 4.
Cost in dollars

Common difference

$1.2

Step-by-step explanation:

Given the total cost, in dollars, given by the function c(p) = 1.2p.

If p = 1

c(1) = 1.2(1)

c(1) = $1.2

If p = 2

c(2) = 1.2(2)

c(2) = $2.4

If p = 3

c(3) = 1.2(3)

c(3) = $3.6

If p = 4

c(4) = 1.2(4)

c(4) = $4.8

Common difference = c2 - c1 = c3 - c2 = c4 - c3

Common difference = 2.4 - 1.2 =  3.6 - 2.4 = 4.8 - 3.6 = 1.2

Hence the common difference is $1.2

439400

step-by-step explanation:

130^2 = 16900

16900*26 = 439400

this is not the answer this is just a question. is this middle school math?
