The cost of sending an overnight package from kansas city to miami is $23.50 for a package weighing up to but not including
1 pound, and $3.80 for each additional pound or portion of a pound. a model for the total cost c (in dollars) of sending the
package is c = 23.50 +3.80lx]. x > 0, where x is the weight (in pounds).
what is the meaning of the coefficient 3.80 in the context of the problem?

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers

391.6 is the correct answer

step-by-step explanation:

let pq = qr = rs = x, and xz = y and zu = z.

if the horizontal lines are parallel, then corresponding segments are in proportion:

substitute:

therefore 3 = y = z.

xu = y + z → xu = 3 + 3 = 6
