Step-by-step explanation:
<u>Blank</u><u> </u><u>C</u> :
Given total = 68
No. of TV news = 13
Therefore, in Internet it would be = Total - TV news
= 68 - 13 = <u>55 (ans)</u>
<u>Blank</u><u> </u><u>D</u> :
No. of Internet news in 7th grade = 55
No. of Internet news in 8th grade = 64
Hence, total Internet base news = 64 + 55 = <u>119 (ans)</u>
<u>Blank</u><u> </u><u>B</u> :
All total = 138
Internet news total = 119
Hence, TV news total = All total - Internet news
= 138 - 119 = <u>19 (ans)</u>
<u>Blank</u><u> </u><u>A</u> :
No. of TV news in 7th grade = 13
Total news in TV = 19
Therefore, no. of TV news in 8th grade = 19 - 13 = <u>6(ans)</u>
<u>Blank</u><u> </u><u>E</u> :
All total = 138
Total of 7th grade news = 68
Hence, total of 8th grade news = 138 - 68
= <u>70 (ans)</u>
