A two-inch by six-inch board costs 24 cents per linear foot. Jennifer needs to purchase 18 boards that are each 10 feet long. What is the total cost of the lumber?

please see the figure to the following pdf warm up -2 problem no 10

$LaTeX$

I'm pretty sure that is just $18\cdot 10\cdot 24= \boxed{\$43.20}$ since I'm pretty sure they would ask for dollars not cents.

The rule is quite flexible. We generally post the solutions anyway.

Why don't you go PM AIME15 regarding this rule?

In that case, why don't you ask him in person to clarify this rule, and to clarify why he hasn't banned us all?
