Mamma Temte bakes six pies a day that cost $2 each to produce. On 21% of the days she sells only two pies. On 40% of the days she sells 4 pies, and on the remaining 39% of the days she sells all six pies. If mama Temte sells her pies for $4 each, what is her expected profit for a days worth of pies? (Assume that any leftover pies are given away - not sold!)
