Need help ASAP. For Finals

a.

b. 55 boxes

c. 5 trips

Step-by-step explanation:

a. Each box weighs 50lbs and the number of boxes is our variable. If you add the worker's weight (180) and the cart's weight (70) you get a constant weight of 250. All of this cannot weigh more than 3000, therefore it can weigh equal to or less than it. Therefore, the equation is .

b. Solve the equation to find the maximum amount of boxes that he can move in one trip, like this:

Therefore, the greatest number of boxes that the worker can move is 55 boxes.

c. Divide the total number of boxes (275) by the amount of boxes that can be taken in one trip (55) to find how many trips it will take. Like this:

275/55 = 5

The worker needs to make 5 trips in order to deliver 275 boxes.

I hope this helps!!

a.) 3000 *no more than symbol* 180 + 70 +50b

the mean and mad

step-by-step explanation:

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
