With the per-unit prices of broccoli (B) and pork rinds (R) equal to $2 and $1, a consumer, George, with an income of $1,000 purchases 300B and 400R. At that point, the consumer's MRSBR = 3 R/1 B. Does this mean that George is at his optimal point? If not, state your reason and suggest a solution. You may also explain with a diagram.
