Final answer:
To find the number of students who prefer cash as a graduation gift, multiply 0.95 by the total number of students surveyed, which is 150. The result is approximately 143 students.
Step-by-step explanation:
To find the number of students who prefer cash as a graduation gift, we need to calculate 95% of the total number of students surveyed.
First, we convert 95% to decimal form by dividing it by 100: 95/100 = 0.95.
Then, we multiply 0.95 by the total number of students surveyed (150): 0.95 * 150 = 142.5.
Since we can't have fractional students, we round the decimal to the nearest whole number.
Hence, approximately 143 students prefer cash as a graduation gift.
