question: Jen is planning to sell her root crops. She has 6 yams which can be sold at $1.5 each, 10 sweet potatoes that cost $2 each, and 4 carrots which cost $1.25 each. If she sells everything, how much will she earn?
answer: Jen can earn $1.5 x 6 = $<<1.5*6=9>>9 for the yams.
  She can earn $2 x 10 = $<<2*10=20>>20 for the sweet potatoes.
  And she can earn $1.25 x 4 = $<<1.25*4=5>>5 for the carrots.
  Therefore, she will earn $9 + $20 + $5 = $<<9+20+5=34>>34 if she sells everything.
