David decides that it is better to create a blend containing 49% NaCl, 30% KCI, and 21% CaCl$_2$, than to buy the pre-prepared blend. Calculate how much it will cost to produce 56 tons of his recommended blend. Don't forget the $5/ton mixing fee. You may find it helpful to refer to Table 2.1 in your lab manual. Treat all values as exact numbers and report the answer to the nearest dollar. 7600 Table FPD.1 Common ice melts.
