A consumer's bundle of consumption goods consists of 40 units of Good A; 20 units of Good B; and 10 units of Good C. The prices for these 3 goods are: $20 for Good A; $10 for Good B; and $5 for Good C. Let the term "utils" refer to the units of utility that consumer receives from consuming goods. Assume that the marginal utility that the consumer received was 300 utils for Good A; 200 utils for Good B; and 100 utils for Good C. Is this an optimal consumption bundle for the consumer? If so, explain why. If not, what should the consumer do?
