This problem is fairly simple. Start by figuring out the fraction of people that were sampled who preferred pretzels by dividing the number of people sampled who preferred pretzels by the total number of people sampled. This would be 45/225, or 0.2. Now that we know the fraction of people that prefer pretzels, 45/225, now simply multiply this fraction by the total number of people attending the reception, 1800. So, 45/225, or 0.2, times 1800 equals 360. The answer is 360 out of her 1800 invited guests are expected to prefer pretzels.
