I believe it's B.
If I'm wrong tell me so I can see what I did wrong.
Rounding is simple:
- If the previous digit is 5-9, round the number to the left of it up a number. If it is 4-0, leave the number to the left of it as it is.
For 82.98, we can round 82 to 83, since 82 is the whole number and the previous digit is 9 (so we round up).
For 169.645, we scratch off 45. Since 6 is in the tenth's place and the previous digit of it is 4, we leave it at 169.64.

Answer:
10
Step-by-step explanation:
we can solve this using basic algebra
We set up the equation using the info that each video costs $5 and that we but 12 of them
12(1 * 5) + x = 70
(Please note: 1x = x)
12(5) + x = 70
60 + x = 70
60 - 60 + x = 70 - 60
x = 10
You multiply then solve for y
<span>(–9.7 • 24) • (–0.25) = –9.7 • (24 • y)
</span>-232.8*(-0.25)=-232.8y
58.2=-232.8y
58.2/-232.8=-232.8y/-232.8
y= -0.25
