Answer:
C. 490.
Step-by-step explanation:
25% = 0.25.
If the number of emails that Ryan and Taylor each received is x emails then Sara received 2x + 0.25 * 2x = 2.5 emails.
So 2x + 2.5x = 882
x = 882/4.5
x = 196.
So Sara received 2.5 * 196
= 490 emails.
52%
52 of 100 blocks are colored
1/5 since your choosing 1 dvd out of 5
and then assuming you DONT put season one back on the shelf you would then have the probablity of 1/4 because you are again choosing 1 dvd out of now 4
575* 0.05 = 28.75
28.75* 2.5(yrs) = 71.875
575+ 71.875 = 646.875
therefore, $646.87
