Madeline hosted a dinner party at her favorite restaurant. She had to pay $15 per guest. The restaurant took $60 off the bill due to a mistake in the order. If the final bill is $675, how many guests attended the dinner party?
Let the number of guest be x. $15 per guest is: 15x There is addition of $60 because of the mistake: +60 The final bill was 675: 675 = 15x + 60 675 - 60 = 15x 615 = 15x x = 615 / 15 x = 41
