Question

Griselda has a farm with some chickens. In the spring, 29 chicks hatched. In the summer, she sold 36 chickens to the farmer next door and ended up with 43 chickens. Using the letter c for the number of chickens Griselda started with, write an equation to represent the word problem.

A. c - 29 + 36 = 43
B. c + 29 - 36 = 43
C. c - 29 - 36 = 43
D. c + 29 + 36 = 43

Answer 1

To represent Griselda's chicken transactions, the equation is c + 29 - 36 = 43, which simplifies to c - 7 = 43. This equation calculates the initial number of chickens before the chicks hatched and some were sold.

Step-by-step explanation:

The question asks us to translate a word problem into an algebraic equation using the letter c to represent the initial number of chickens Griselda had on her farm. To approach the problem, we need to account for the chickens that hatched and the chickens that were sold.

Griselda started with c chickens, and 29 chicks hatched, increasing the number of chickens to c + 29. Then, she sold 36 chickens, so we subtracted 36 from the total, getting c + 29 - 36. After these transactions, Griselda ended up with 43 chickens. Therefore, the correct equation that represents this situation is:

c + 29 - 36 = 43

This simplifies to:

c - 7 = 43

So, the correct answer is option B: c + 29 - 36 = 43.
