Unit Digit Problems: Finding Numbers Ending in 4 Greater Than 76

To solve this problem, we will evaluate each provided choice to see if it meets the given conditions. The number must be greater than 76 and have a unit digit of 4.

Evaluation of the choices:

• Choice 1: $44$

  The unit digit of 44 is 4, but 44 is not greater than 76. Therefore, this choice does not satisfy both conditions.

• Choice 2: $84$

  The unit digit of 84 is 4, and 84 is greater than 76. This choice satisfies both conditions.

• Choice 3: $94$

  The unit digit of 94 is 4, and 94 is greater than 76. This choice satisfies both criteria.

• Choice 4: "Answers (b) and (c) are correct."

  Both choices (b) and (c) satisfy all the specified conditions of ending in 4 and being greater than 76.

Thus, for conclusions:

The numbers 84 and 94 meet the required criteria and the correct choice is "Answers (b) and (c) are correct."

Therefore, the solution to the problem is Answers (b) and (c) are correct.
