conversations.value: Pauline will make tacos for dinner. She bought a box of taco shells that cost $5, 4 bell peppers that cost $1.5 each, and 2 pounds of meat that cost $3 per pound.  How much did she spend in all?
  What is the solution?

conversations.value: She spent 4 x $1.5 = $6 for the four bell peppers.
  She spent 2 x $3 = $6 for the 2 pounds of meat.
  So, Pauline spent $5 + $6 + $6 = $17 in all.
