First find the total cost of the beef: $11/pound * 3 pounds = $<<11*3=33>>33
Then find the total cost of the fruits and vegetables: $4/pound * 8 pounds = $<<4*8=32>>32
Then find the total cost of the spices: $6/jar * 3 jars = $<<6*3=18>>18
Now add the cost of all the items to find Martha's total spending: $33 + $32 + $18 + $37 = $<<33+32+18+37=120>>120
Now divide 50 points by $10 to find now many points Martha gets per dollar: 50 points / $10 = <<50/10=5>>5 points/dollar
Now multiply this exchange rate by Martha's total spending to find how many points she gets before the bonus: $120 * 5 points/dollar = <<120*5=600>>600 points
Finally, add the 250 point bonus Martha gets for spending more than $100: 600 points + 250 points = 850 points
