Question

In 1920, a woman had 4 daughters. In 1950, each daughter had 3 daughters. In 1980, each of their daughters had 3 daughters. Finally, in 2010, each of their daughters had 3 daughters.
How many daughters were born in 2010? Explain how you determined your answer.

Answer 1

Answer:

108

I determined my answer by multiplying 4 x 3 x 3 x 3 = 108

Step-by-step explanation:

daughters born in 1950 = 4 x 3 = 12

daughters born in 1980 = 12 x 3 = 36

daughters born in 2010 = 36 x 3 = 108
