This is a unit-conversion problem involving yards, feet, and inches. First, convert yards to feet. Since 1 yard equals 3 feet, multiply: 2.5 × 3 = 7.5 feet. Next, convert feet to inches using the given conversion of 12 inches per foot. Multiply: 7.5 × 12 = 90 inches. Therefore, the correct answer is C. Option A (72 inches) represents only 6 feet. Option B (45 inches) results from converting yards directly to inches incorrectly. Option D (54 inches) represents 4.5 feet. On the NEX exam, multi-step measurement conversions are common, and accuracy depends on converting one unit at a time rather than skipping steps.

This question tests calculation of the mean. First, add all the infant weights:

8.5 + 11 + 7 + 5 + 7 + 4.5 + 9 + 8 = 60 pounds.

Next, divide the total by the number of infants: 60 ÷ 8 = 7.5? Recheck carefully: 60 ÷ 8 = 7.5, but reviewing the answer choices and recalculating the sum more carefully:

8.5 + 11 = 19.5

19.5 + 7 = 26.5

26.5 + 5 = 31.5

31.5 + 7 = 38.5

38.5 + 4.5 = 43

43 + 9 = 52

52 + 8 = 60

60 ÷ 8 = 7.5, which corresponds to option C.

This problem tests fractions, percentages, and subtraction of parts from a whole—common NEX skills. First calculate the amount spent on decorations:

of $500 equals $62.50. Next calculate the food cost: 25% is equivalent to 0.25, and 0.25 × 500 = $125. Add these two expenses together: $62.50 + $125 = $187.50. This represents the portion of the budget already allocated. To find the remaining budget for venue and entertainment, subtract this amount from the total budget: $500 − $187.50 = $312.50. Therefore, option A is correct. Option B assumes only one category was subtracted. Option C results from incorrect fraction conversion. Option D represents the amount already spent, not the remainder. NEX questions often require careful step-by-step subtraction after converting fractions and percentages correctly.

This is a multi-step dosage and unit-conversion problem. Each bottle contains 120 mL, and the infant drinks half a bottle per feeding. Half of 120 mL is 60 mL. The infant has 6 feedings, so total intake is 60 × 6 = 360 mL. Convert milliliters to ounces using the given conversion: 360 ÷ 30 = 12 ounces. Therefore, option C is correct. Option D represents milliliters, not ounces. Option B incorrectly doubles the intake. The NEX frequently includes pediatric feeding and medication scenarios requiring careful tracking of totals and unit conversions.
