She orders 2 sandwiches that are $7.75 so they cost 2*$7.75 = $<<2*7.75=15.50>>15.50
The brie is three times more expensive than the $4.00 salami so the brie costs 3*$4 = $<<3*4=12.00>>12.00
She buys 1/4 pound of the olives that costs $10.00 a pound so they cost .25*$10 =$<<1/4*10=2.50>>2.50
She buys 1/2 pound of feta that costs $8.00 a pound so it costs .5*$8 = $<<1/2*8=4.00>>4.00
The salami is $4.00, the brie is $12.00, olives are $2.50 and the feta is $4.00 and the sandwiches are $15.50 for a total of $4+$12+$2.50+$4+$15.50 = $<<4+12+2.5+4+15.50=38.00>>38.00
Adding the french bread gives $38.00+$2.00 = $<<38+2=40>>40
