Henry starts the day with $30. He and his sister go to the fair. He pays for his own admission of $10, but fails to notice that $15 falls out of his wallet while he is paying. His sister lends him $10 so that he can still enjoy the fair. Write the equation that illustrates his day's financial events.

• $30 - $10 - $15 + $10 = $15

• $30 + $10 - $15 + $10 = $25

• $30 - $10 + $15 + $10 = $30

• $30 - $10 - $15 - $10 = $5
