The probability of Jamie picking a blue marble is greater. The ratio of this probability would be 7:3
Because we need that m(t) is greater than $3 billion we simply write:
0.42t + 0.532 > 3
Now we proceed to solving:
0.42t > 2.468
t > 2.468/0.42
t> 5.876
If we want to make t as integer that means that from 2016 (6 years after 2010) more than $3 billion will be spent for streaming music services
You need to divide 6 by 4/5.
6÷4/5
6 x 5/4
