Stefan goes to a restaurant to eat dinner with his family. They order an appetizer that costs $10 and 4 entrees that are $20 each. If they tip 20% of the total for the waiter, what is the total amount of money that they spend at the restaurant?

How much do the entrees cost? ** The total cost of the entrees is 4 * $20 = $<<4*20=80>>80.
What is the total cost of the dinner? ** The total cost of the dinner is $80 + $10 = $<<80+10=90>>90.
How much is the tip? ** The tip is $90 * 0.20 = $<<90*0.20=18>>18
What is the total cost with tip? ** The total cost with tip is $90 + $18 = $<<90+18=108>>108
