Answer: B) 1 1/2 cups of flour: 1 cup of sugar
Explanation:
When you look carefully at the graphed line, it intersects the grid at 1 1/2 on the vertical scale for Flour and at the same point, it intersects the 1 on the horizontal scale for Sugar. That is answer B.
Answer A is a close miss! When you follow the grid line across from 2 on the vertical scale, you see that the graphed line crosses it at just a little less than 1 1/2.
