prompt: Samanta is planning a party for her friend Marta. She decided to raise some money among the guests she invited, to buy Marta a gift. Every participant gave Samanta $5 for this purpose and she herself put in $10. The gift cost was lower than expected, so there was $15 leftover. What was the price of the gift, if there were 12 guests invited?

messages.content: From all the guests Samanta got $5/guest * 12 guests = $<<5*12=60>>60.
  Including money Samanta put herself, she had $60 + $10 = $<<60+10=70>>70.
  The cost of the gift was $70 - $15 = $<<70-15=55>>55.
