Step 1 :In a survey about the drinking age, the number of adults against lowering the drinking age to 18 was 740, which was about 70% of the adults in the survey. We are asked to find the total number of adults surveyed.
Step 2 :We know that 740 adults were against lowering the drinking age to 18 and this represents 70% of the total number of adults surveyed. We can set up the equation \(740 = 0.70 \times \text{total}\) to solve for the total number of adults surveyed.
Step 3 :Solving the equation gives us the total number of adults surveyed as approximately 1058.
Step 4 :So, the total number of adults surveyed is \(\boxed{1058}\).
