A recipe for crispy rice treats results in a mixture that fills a 9-inch by 13-inch pan to a depth of one inch. If a crispy rice treats mixture resulting from 1.5 times the original recipe is poured into a pan that is 12 inches by 15 inches, to what depth, in inches, will the pan be filled? Express your answer as a decimal to the nearest hundredth.

Volume of 1 'batch' =   9 * 13 * 1 = 117 in3

   volume of 1.5 batch   =   1.5 * 117 = 175.5  in3

 

12 * 15  * d   = 175.5

d = depth = .975 inch ~~  .98 inches
