anonymous · Answer

its fine david :)

davidusa · Answer

i mean id be able to figure it out but right now i dont have time im busy.

anonymous · Answer

The weight must be less than or equal to the limit, 2200 lb.

40 pounds per box means 40b, where b is the number of boxes. Tack on Michelle's weight and the push cart's weight and set it less than or equal to the weight limit.

anonymous · Answer

so the arrow points to the left?

davidusa · Answer

yes

anonymous · Answer

Yes

anonymous · Answer

and there's a closed circle on 55?

anonymous · Answer

Is there?

110 + 10 + 40b <= 2200
120 + 4b <= 2200
4b <= 2080

anonymous · Answer

i think so im not sure though im not good with inequalities

anonymous · Answer

Pretend the inequality sign is just an equals for now and use algebra.

4b <= 2080

anonymous · Answer

okay so ill divide 2080 by 4 and get 520

anonymous · Answer

Oops, that should be 40b <= 2080.
You did it right, but my error got the wrong answer. It would get you 52. So you were right.

The sign is less than or equal to. What kind of circle does this make?

anonymous · Answer

a closed one

anonymous · Answer

so i only chek two of the answers? the closed circle is 52 and the arrow points left

anonymous · Answer

The arrow points left and there's a closed circle, which means it contains 52 and the numbers less than it. There's a third answer you need to check. It can't be a circle on 55, and it can't be the arrow points to the right.

anonymous · Answer

the solution set contains the number 51

anonymous · Answer

point not number

anonymous · Answer

Yes! Those are the three you check.
