An online store charges a few of $4.50 for shipping. There is an additional charge of $0.50 for each pound the item weighs. How much does the store charge to ship a hammock that weighs 10.54 pounds?

The store charges $9.77 to ship a hammock that weighs 10.54 pounds.

Step-by-step explanation:

4.50 (shipping cost)

0.50 (per 1 pound)

w = weight in pounds

       w=10.54

4.50+0.50w= total cost

        sub in 10.54 for w

        remember order of operations (PEMDAS)

4.50 + 0.50 (10.54) = 4.50 + 5.27 = 9.77

The store charges $9.77 to ship a hammock that weighs 10.54 pounds.

answer: integers are just whole numbers: positive, negative, and zero.

i = {-∞, -2, -1, 0, 1, 2, 3, ∞}

let x = 1st integer

let y = 2nd integer

x = 3y + 17   {equation 1}

xy = -24         {equation 2}

substitute 3y+17 in place of x n equation 2

and solve for y.

(3y+17)y = -24

3y2 + 17y = -24

3y2 + 17y + 24 = 0

from quadratic equation:

y = [-17±√(172-4(3)(24))]/(2(3))

y = (-17 ±√1)/6

y = (-17+1)/6   or     y = (-17-1)/6

y = -16/6           or     y = -18/6

y = -2 2/3         or   y = -3

since we are dealing with

y = -3

x = 3y+17 = -9+17 = 8

the integers are -3, 8
