(b) Since we are still receiving one extra coupon for each consecutive day, $\sum\limits_{i=1}^k i$ can still represent the number of coupons received. However, the value of the coupons is: $1 + 2 + 4 + 8 + ... + 2(n-1)$ which can be represented as $\sum\limits_{i=1}^n 2^(n-i)$.
\smallskip
We must multiply the quantity and the value together to get the total value resulting in: $\sum\limits_{i=1}^n
i * 2^(n-i)$ i*2^(n-i)$
