Final answer:
The algebraic expression for 3c greater than 3y is b) 3c > 3y. This shows that the value of 3c exceeds the value of 3y.
Step-by-step explanation:
To write the algebraic expression for 3c greater than 3y, we need to use the greater than symbol (>). The expression 3c > 3y correctly represents that 3c is more than 3y. Therefore, the answer is b) 3c > 3y.
If we were to express this in terms of an equation, and we knew the value for y, for example, y = 30.00, we could substitute this into the expression to see what the value of c would need to be to make the inequality true. However, no specific equation is needed for the simple inequality expression that's been asked for.
