James decides to make a bathtub full of jello. For every pound of water, you need 1.5 tablespoons of jello mix. The bathtub can hold 6 cubic feet of water. Each cubic foot of water is 7.5 gallons. A gallon of water weighs 8 pounds. A tablespoon of jello mix costs $0.50. How much did he spend to fill his tub?
Think hard. Detailed solution:
270
The tub has 6 * 7.

5 = 45 gallons.

That would weigh 45 * 8 = 360 pounds.

So he needs 360 * 1.

5 = 540 tablespoons of jello mix.

So he spent 540 *.

5 = $270.

The final answer: 270
