Problema Solution
A lady in a restaurant has only $43.00. If she pays 7% sales tax and wishes to leave a 10%tip on the total bill (meal plus tax), what is the maximum price of the lunch she can order?
Answer provided by our tutors
let 'x' be the cost of the lunch
the cost of the meal x + 7% taxes of x + 10% tip <= $43
x + 0.07*x + 0.10(x + 0.07*x) <= 43
x<= 4300/117
x<= 36.5336
the maximum price of the lunch she can order is $36.5336.
