conversations.value: This math problem has got me stumped: Sara wants to buy herself a new jacket and 2 pairs of shoes. The jacket she wants costs $30 and each pair of shoes cost $20. Sara babysits the neighbor's kids 4 times, earning $5 each time she babysits them. Her parents pay her $4 each time she mows the lawn. If Sara already had $10 saved before she started babysitting, how many times must she mow the lawn before she can afford the jacket and shoes?
  Can you show me the way?

conversations.value: Both pairs of shoes will cost a total of 2 * $20 = $40.
  Sara will need to save a total of $30 + $40 = $70 to buy everything that she wants.
  Sara has earned 4 * $5 = $20 from babysitting.
  Between her savings and the babysitting, Sara has already saved $10 + $20 = $30.
  Sara needs to earn an additional $70 - $30 = $40 from mowing the lawn to afford her clothes.
  Sara must mow the lawn $40 / $4 = 10 times to afford to buy the jacket and shoes.
