Question

A farmer sees 56 of his cows out of the barn. He knows that he has 83 cows altogether. Let c represent the number of cows still in the barn and write an equation to represent this problem. Can c = 33?

A. 56 + 83 = c; no

B. c + 33 = 56; yes

C. 83 + c = 56; no

Answer 1

56 + c = 83 equation

subtract 56 from each side

c = 27

c cannot equal 33
