Questions & Step-by-Step Solutions
A national survey shows that 70% of people support a new policy. If 1,000 people were surveyed, how many do not support the policy? (2019)
Step 1: Understand that 70% of people support the new policy.
Step 2: Know that 1,000 people were surveyed.
Step 3: Calculate the number of supporters by finding 70% of 1,000. This is done by multiplying 1,000 by 0.70 (which is 70% as a decimal).
Step 4: Perform the calculation: 1,000 * 0.70 = 700. So, 700 people support the policy.
Step 5: To find out how many people do not support the policy, subtract the number of supporters from the total number of people surveyed: 1,000 - 700.
Step 6: Perform the subtraction: 1,000 - 700 = 300. So, 300 people do not support the policy.
