Edison had 1,093 patents across a wide variety of technology areas. He is one of the most versatile and prolific inventors ever. Hold the anchovies please! The tax rate is 6.7% and the student discount is 15%. They paid $12.96 plus 87¢ tax for lunch for two. Therefore, the tax rate is 87¢ ÷ 12.96 = .067 = 6.7%. Since the total bill for the student was $5.88, the bill for her buffet and drink was $5.51. Let x = charge for her buffet and drink. Then x + .067x = 5.88. So, 1.067x = 5.88, and x = 5.51. Since Mr. and Mrs. P each were charged $6.48 for a buffet and drink, the students got a discount of $6.48 – $5.51 = 97¢. So, the discount rate for students is 97¢ ÷ $6.48 = 0.14969 = 15%.
