Final answer:
Without a clear mathematical expression, the answer assumes the variable 's' is to be divided by three friends. For s = 304.3, each friend gets 101.43 ounces, and for s = 250, each friend gets approximately 83.33 ounces.
Step-by-step explanation:
The student's question seems to contain a mathematical expression that is not clearly stated. However, it suggests that there's an expression related to dividing 100 fluid ounces of syrup among Enrique and his two friends, and we're asked to evaluate this expression for different values of an unknown variable 's'. Without a clear expression, we cannot provide a specific answer. If 's' represents the total earnings from selling the syrup, and assuming that the expression to evaluate is s ÷ 3 since the syrup is being divided by three friends, we would then divide the given values of 's' by 3 to find how much syrup each person receives.
For s = 304.3, each friend would receive 304.3 ÷ 3 = 101.43 fluid ounces.
For s = 250, each friend would receive 250 ÷ 3 = approximately 83.33 fluid ounces.
This interpretation relies on an assumed expression as the original expression is missing from the student's question.
