[tex]\text {Hello! Let's Solve this Problem!}[/tex]
[tex]\text {Because we are rounding to the nearest billions place we would under the 8}[/tex][tex]\text {and point an arrow to the number next to it which is 4.}[/tex]
[tex]\text {If the number is 5 or more we raise the score. 4 or less let is rest. This means}[/tex][tex]\text {that if the number is 5 or more we add 1. If the number is 4 or below the}[/tex][tex]\text {number stays the same.}[/tex]
[tex]\text {5 is greater than 4 so this means 4 stays the same.}[/tex]
[tex]\text {Your Answer Would Be:}[/tex]
[tex]\huge\boxed {\text {B) 8,4000,000,000}}[/tex]
