Mitchell order a plain Turkey sandwich and a drink for lunch. The drink is 2.95. Instead he is served the super sandwich with lettuce tomato and mayonnaise. The restaurant manager takes 15% of the price of the sandwich. Wrote an equation to determine the Original process of the sandwich x if his new bill is 8.86

Respuesta :

drink: $2.95

discount: 15%                   (let s = cost of turkey sandwich)

bill: $8.86

discount = 15%s = 0.15s

m - 0.15m = 0.85s

equation: $8.86 = 2.95 + 0.85s
