srslly its easy just look at it
Let X be the number of households.
so they sent the promotional material to 21% which means 0.21X number of households get the material.
out of the 0.21x households only 0.14 respond which is
0.14(0.21x) = 0.0294x or 2.94%
2.94% is the probability that a household receives and responds.
10 percent of 140 pounds is 14 pounds. You can prove this with the operation of 0.1 (which is 10 percent in decimel) times 140. This will grant you 14.
The correct answer is 14
