A delivery person uses a service elevator to bring boxes of books up to an office. The delivery person weighs 160 lb and each box of books weighs 60 lb. The maximum capacity of the elevator is 1110 b. How many bees of books can the delivery person bring up at one time? The delivery person can bring up boxes of books. (Type a whole number)
To find out how many boxes of books the delivery person can bring up at one time, we need to subtract the delivery person's weight from the maximum capacity of the elevator and then divide by the weight of each box.
The maximum capacity of the elevator is 1110 lb.
The delivery person weighs 160 lb.
The weight of each box is 60 lb.
1110 - 160 = 950 lb of weight that can be allocated for the boxes of books.
950 / 60 = <<950/60=15>>15 boxes of books the delivery person can bring up at one time.
So, the delivery person can bring up 15 boxes of books at one time.
To find out how many boxes of books the delivery person can bring up at one time, we need to compare the total weight of the delivery person and the boxes of books to the maximum capacity of the elevator.
The delivery person weighs 160 lb, and each box of books weighs 60 lb. Let's represent the number of boxes of books as 'x'.
The total weight of the delivery person and the boxes of books is given by the equation:
160 + 60x
This total weight should be less than or equal to the maximum capacity of the elevator, which is 1110 lb.
So we can set up the following inequality:
160 + 60x ≤ 1110
To find the number of boxes of books the delivery person can bring up, let's solve this inequality step-by-step:
160 + 60x ≤ 1110
Subtract 160 from both sides:
60x ≤ 950
Divide both sides by 60:
x ≤ 15.833
Since x represents the number of boxes of books, it should be a whole number. Therefore, the delivery person can bring up a maximum of 15 boxes of books at one time.
