To maximize his utility, Caesar should allocate his budget in such a way that the marginal utility per dollar spent on each good is equal. In this case, the marginal utility per dollar of soft drinks is 10 (12 utils / $1.20), while the marginal utility per dollar of chips is 8 (8 utils / $1). Therefore, Caesar should buy more soft drinks and fewer chips since he gets more utility per dollar spent on soft drinks. Additionally, the fact that soft drinks have fewer calories is irrelevant to the decision of how to allocate his budget for maximum utility.
