Question

I got this one wrong please help I don't understand must so work...

Answer 1

I believe the answer would be D because it's telling u that item p weighs 2kg and that the box itself weighs 1 kg but the amount she can carry is 10kg so that means that the item p and the box weight together is less than the amount she can carry

Answer 2

If each item Kathy puts in the box weighs 2 kg, then the weight of p items will be 2p kilograms. Since the box weighs 1 kg, the total weight in kilograms will be ...

... 2p + 1

Kathy wants that value to be less than or equal to 10 kg, so her inequality will be

... 2p + 1 ≤ 10 . . . . . corresponds to selection D
