Create a JavaFX application that lets the user enter the food charge for a meal at a restaurant. When a button is clicked, the application should calculate and display the amount of an 18 percent tip on the total food charge, 7 percent sales tax, and the total of all three amounts. For example, if $20 is entered as a food charge for a meal then $3.6 should be displayed for the tip, $1.4 should be displayed for sales tax, and $25 should be displayed as a total of all three amounts.

the warning light flashes for a second or two when the engine starts. if it stays on, there's must be something wrong with the coolant. you should never dare to continue driving when the light is on. pull over as soon as possible and shut the engine off.
