Answer:
The correct option is C.
Step-by-step explanation:
From 1960 to 1970, the consumer price index (CPI) increased from 29.6 to 38.8.
Let the macaroni and cheese dinner cost $x in 1960.
If a macaroni and cheese dinner cost $0.37 in 1960 and the price of macaroni and cheese increased at the same rate as the CPI from 1960 to 1970, then
The macaroni and cheese dinner cost is $0.485 in 1970.
The price of a macaroni and cheese dinner increase from 1960 to 1970 by
The price of a macaroni and cheese dinner increased by $0.12 from 1960 to 1970.
Therefore the correct option is C.

You can divide a triangle using medians. Let's name triangle ΔABC shown in figure 1. So you must start at one of the vertices and then bisect the opposite side. Let's start with the point A and then we bisect the opposite side. Then the length from B to D is equal to the length from D to C. So let's take the point B and then we bisect the opposite side. Then the length from A to E is equal to the length from E to C. The same reasoning happens with the point C. So we have, in figure 2, the triangle ΔABC divided into six triangles which all have the same area.
