Question

Please help me someone.

Answer 1

A). +34.98 +51.02 +51.22. -5.23 -10.22 -7.89a

B). -10.22, -7.89, -5.23, +34.98, +51.02, +51.22. They are ordered this way because first of all a negative number is always less than a positive. Then, the farther you go left on a number line, the least the number is. -10.22 is the farthest, so it's the least, and so on. Then, the farther right you go, the greater the number is. +51.22 is the farthest right, and so on.

C). $241.88 because you do 128+34.98=162.98. Then you do 162.98+51.02=214. Hen 214+51.22=265.22. Then you have to separately add 5.23+10.22=15.45. Then 15.45+7.89=23.34. Then you take 265.22-23.34 and you get your grand total of 214.88.
