Problema Solution
After a lady is seated in a restaurant, she realizes that she only has $50.00. If she must pay 7% sales tax and wishes to leave a 20% 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
x + 0.07*x + 0.20(x + 0.07*x) = 50
x= $38.9408
the maximum price of the lunch she can order is $38.9408.
