Hint for process of elimination: It can help you to draw boxes, where each box represents $latex \dfrac{1}{2} $ hour. Write the number 20 in each box until you get to 150 pictures. Then just count boxes.
It will also help you to think intuitively about this problem. You know how time works, and you know what twenty doggy pictures looks like. Approximate. How many half hour time slots will it take to draw 150 doggies?

Hint for process of elimination: In the vast majority of cases, the SAT problem creators are very careful to make solutions realistic. You may recognize 5 km, or 3.1 miles, to be the standard distance for a 5K, a very common race frequently ran or walked for charity or in local or school competition across the United States. A 5K can be run in 15 minutes for the fastest high school runners, or walked at a comfortable pace in less than one hour. Use this to eliminate the two answers that do not make sense.

Hint for process of elimination: The problem asked for the price, in cents, of 1000 fluid ounces of diesel fuel. We are told in the problem, and you may also remember from science class, that there are 128 fluid ounces in one gallon. That means there are 1280 fluid ounces in ten gallons. 1000 ounces is a little less than ten gallons, but not much less. It follows that the price in dollars of the 1000 fluid ounces is a little less than $latex D &s=1$. Therefore, the price in cents of 1000 fluid ounces is a little less than $latex 100D &s=1$. The only answer with a coefficient of D that is close to but less than $latex 100 &s=1$ is choice D.
