Answer

Explanation:

Step1: Set up the equation

The cost of each magnet is $3 and the number of magnets is $y$, so the cost of magnets is $3y$. The shipping fee is $5 and the total cost is $455. So the equation is $3y + 5=455$.

Step2: Solve for $y$

Subtract 5 from both sides of the equation: $3y+5 - 5=455 - 5$, which simplifies to $3y = 450$.

Step3: Isolate $y$

Divide both sides of the equation $3y = 450$ by 3: $y=\frac{450}{3}=150$.

Answer:

C. $3y + 5 = 455$, $y = 150$
