You go to dinner and decide to leave a 15% tip for the server. You had $55 when you entered the restaurant.
a. Make a table showing how much money you would have left after buying a meal that costs $15, $21, $24, or $30.
b. Write a function rule for the amount of money m you would have left if the meal costs c dollars before the tip.
c. Graph the function rule.
f(c) = 55 - c*1.15
There's your function, I'm really lazy and don't want to make a table out of that so just plug 15, 21, 24, and 30 in for c and as for the graphing of the function, just go to desmos.com and plug in the function
Also if you have a smartphone, you may want to download the app for Desmos (easy visual graphing calculator) and Mathaway (pretty much gives you the answers to any problem and how to get them). GLHF ;)
