In a certain lottery drawing, two balls are selected at random from a container with 10 balls, numbered from 1 to 10, inclusive. If the winner of the lottery is awarded a cash prize in the amount of $1,000 times the product of the numbers on the two selected balls, which of the following is a possible amount of the cash prize given to the winner?
Choices
A) $9 x 10^4  B) $9.90 x 10^6  C) $1.00 x 10^7  D) $1.05 x 10^7  E) $9.90 x 10^7
The max product of any two balls can be 9 * 10 = 9900 = 9 * 10   If we multiply it by $1000 the max amount will be 9 * 10^4.   $9 x 10^4
