Final answer:
The algebraic expression for '12 more than the product of 47 and a number' is '47y + 12', representing the product first followed by the addition.
Step-by-step explanation:
The algebraic expression for 12 more than the product of 47 and a number would be written as 47y + 12. This is because you first find the product of 47 and the variable (let's call it y), and then add 12 to that product. So the algebraic expression 47y represents the product of 47 and the number, and simply adding 12 completes the expression as required.
