<human>:  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 $0.50. How much did he spend to fill his tub?
<bot>: How many gallons of water does the tub hold? ** The tub has 6*7.5=<<6*7.5=45>>45 gallons
How much does the water weigh? ** That would weigh 45*8=<<45*8=360>>360 pounds
How many tablespoons of jello mix does he need? ** So he needs 360*1.5=<<360*1.5=540>>540 tablespoons of jello mix.
How much did he spend? ** So he spent 540*.5=$<<540*.5=270>>270
