The ninth grade students of a school organized a pancake breakfast, held a karaoke contest, and sold raffle tickets to raise money for a field trip. They raised a total of $1,025. The money raised from the karaoke contest was 3 times the money raised from the breakfast. The money raised from the sale of raffle tickets was $150 less than the money raised from the breakfast. The following equation represents this information, where x is the amount of money raised from the pancake breakfast.

x + 3x + (x − 150) = 1025
How much money, in dollars, did the ninth graders raise from the karaoke?
