The bill for Mr. Wilson’s diner meal is $25.50. As a tip, Mr. Wilson gives the server 20% of the meal’s cost. What is the total amount Mr. Wilson’s pays, including tip?

$30.60

Step-by-step explanation:

What we know:

The bill for Mr. Wilson's diner meal is $25.50.

He gives a 20% tip to the waiter.

To figure out this tip, multiply 1/5 by 25.5.

1/5 * 51/2

51/10 = $5.10 tip.

Here, it's asking for the total, including the $5.10 tip. So, add $5.10 to $25.50 for $30.60 total, including the tip.

(For a simpler method *multiply 6/5 by $25.5)

2x^2+5x+17
