G=R-C 3,4=R-5,2 R=5,2+3,4=8,6cad 8,6*12=10,3,20
12)
Ricavo $R= 20×35+30×48 = 700+1440 = 2140$ €;
totale costi $C= R-G = 2140-805 = 1335$ €.
10)
Ricavi (R) = costi (C) + guadagni (G)
quindi:
ricavo totale $\small R = 12×5,20+12×3,40 = 12(5,20+3,40) = 12×8,60 = 103,20$ €.
11)
Totale costi $\small C= 0,90+1,50+0,20+1+2,80 = 6,40$ €;
ricavo totale $\small R= C+G = 6,40+6,50= 12,90$ €.
13)
Guadagno $G= R-C;$
$G= \left[(52-13)×46+13(46-11)\right]-1456$
$G= \left[39×46+13×35\right]-1456$
$G= \left[1794+455\right]-1456$
$G= 2249-1456=793$ €.
