A.![3x+4=28](/tpl/images/0460/5687/cd4ca.png)
Step-by-step explanation:
Let x be the number.
We have been given that 3 times a certain number is increased by 4.
3 times the number will be 3x and after increasing it by 4 will make our number
.
We are also told that the result of the above process is 28.
So we can set our given expression equal to its result as:
Therefore, option A is the correct choice.
Let us solve for x.
Therefore, the number is 8.
