Jessle will pack a sultcase with books. The total weight of the suitcase and books can be no more than 50 pounds. The empty sultcase weighs 5.7 pounds. Each book weighs 2.4 pounds.
What is the greatest number of books that Jessie can pack in the suitcase? Enter the answer in the box.

HURRY NEED ANWSER PLS

First subtract the weight of the suitcase from the total weight they case can weigh when full:

50 - 5.7 = 44.3 pounds

This means she can put 44. 3 pounds of books in the suitcase.

Now find the number of books:

Divide the total Weight of what she can fit in the suitcase by the weight of each book:

44.3 / 2.4 = 18.458

Because the answer has a decimal you round down to the whole number, because if you rounded up it would weigh more than allowed.

The answer is she can carry 18 books

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer

i agree because i see the other persons thinking is clear
