messages.content: She bought 1.5 pounds of chicken for $6.00/pound so that's 1.5*$6 = $<<1.5*6=9.00>>9.00
  She bought 4 sweet potatoes at $0.75 each so that's 4*$0.75 = $<<4*0.75=3.00>>3.00
  She bought 2 heads of broccoli for $2.00 each so that's 2*$2 = $<<2*2=4.00>>4.00
  The chicken is $9.00, lettuce is $3.00, tomatoes are $2.50, the sweet potatoes are $3.00, broccoli is $4.00 and Brussel sprouts are $2.50 for a total of $9 + $3 + $2.50 + $3 + $4 + $2.5 = $<<9+3+2.5+3+4+2.5=24.00>>24.00
  To get free delivery she needs to spend $35.00, and she already has $24.00 in her cart, so she needs to spend an extra $35-$24 = $<<35-24=11.00>>11.00
