Question

Mr. Caldon bought 2 dozen of eggs at the supermarket. When he got home, he fried three eges. Which equation represents the number of eggs (E) Mr. Caldon has left?
B-2x 3-12
R 12 X 3+2
E-3x2 +12
E-2 x 12 - 3

Answer 1

Answer: E- 2x12 - 3

Heres how:

Mr. Caldon buys two dozen eggs. a dozen is 12, so two dozen is 12x2, which is 24.

He fries 3 eggs, meaning he uses them.

To find how many he has left, subtract how many he used from what he had.

In Algebra, we represent this as 12x2 - 3
