b. If the weight of the kitten continues to increase linearly for 3 months, predict the kitten's weight 10 weeks After birth.

A) a. $a _ { n } = 0.27 n + 0.43$
b. $2.7 \mathrm { lb }$

B) a. $a _ { n } = 0.27 n + 0.7$
b. $2.7 \mathrm { lb }$

C) a. $a _ { n } = 0.27 n + 0.43$
b. $3.13 \mathrm { lb }$

D) a. $a _ { n } = 0.27 n + 0.7$
