For each order, a certain company charges a delivery fee \(d\) that depends on the total price \(x\) of the merchandise in the order, where \(d\) and \(x\) are in dollars and
\(\begin{cases} d = 3 \;\text{if} \; 0<x\le 100,\\
d = 3 + \dfrac{x-100}{100} \; \text{if} \; 100<x \le 500,\\
d = 7 \; \text{if} \; x>500.\end{cases}\)
If George placed two separate orders with the company, was the total price of the merchandise in the two orders greater than \(\$499?\)
(1) The delivery fee for one of the two orders was \(\$3.\)
(2) The sum of the delivery fees for the two orders was \(\$10.\)
