Answer:
A package that weighs 5 pounds will cost $15 for both options.
Explanation:
The equation for the cost of the first shipping option is y = 5 + 2x, where x represents the amount of pounds of the package. The cost, y, increases by $2 per pound of the package. So, if the package weighs 5 pounds, the cost of the first option would be y = 5 + 2 * 5 = $15.
The equation for the second shipping option is y = 15, representing a one-time fee of $15 to send the box. The cost is fixed at $15 regardless of the weight of the package.
Therefore, if the package weighs 5 pounds, the cost of both shipping options would be $15, and the two options would cost the same.
