The new price for each lemon after increasing by $4 is $8+$4 = $<<8+4=12>>12
For the 80 lemons, Erick received $12*80 = $<<12*80=960>>960
The price of each grape increased by 1/2*$4 = $<<1/2*4=2>>2
The new price at which Erick sold his grapes is $7+$2 = $<<7+2=9>>9
For the 140 grapes, Erick collected 140*$9 = $<<140*9=1260>>1260
From the sale of all of his fruits, Erick received $1260+$960 = $<<1260+960=2220>>2220
