conversations.value: Martha collected 90 cans while Diego collected 10 more than half the cans collected by Martha. If both of them should collect a total of 150 cans for their project, how many more cans do they need to collect?

conversations.value: Half the cans collected by Martha is 90/2 = 45
  So, Diego collected 45 + 10 =55 cans.
  Martha and Diego collected 90 + 55 = 145 cans together.
  Thus, they need to collect 150 - 145 = 5 more cans.
