Help please I need to know now Help

a. w = weight (lbs)

b. cost = 1.45w + 3.25

c. w = 4 lbs

Step-by-step explanation:

we can say that variable w stands for the weight of the package (in pounds).

using this, we know that the cost to ship a package is going to be equal to $1.45 per pound or 1.45w, but we can't forget about the service fee. the service fee doesn't change, so we just add that to our equation to get

cost = 1.45w + 3.25

lastly, we can solve

(isolate w by subtracting 3.25 from both sides)

(divide both sides by 1.45 to get w by itself)

(evaluate)

(don't forget units)

w = 4 lbs

hope this helps :)
