Mrs. Wong bought 3 medals: one gold medal, one silver medal and one bronze medal for the upcoming math contest. One gold medal is twice as expensive as one silver medal and one silver medal is 3 times as expensive as one bronze medal. She spent $35.00 altogether. How much was the gold medal?

Answer

Let the cost of the bronze medal be x.

Then, the cost of the silver medal is 3x (since it is 3 times the bronze).

The cost of the gold medal is 2(3x) = 6x (since it is twice the silver).

The total cost is: x + 3x + 6x = 10x.

We know that 10x = $35.00.

So, x = $3.50.

The cost of the gold medal is 6x = 6 * $3.50 = $21.00.
