Answer :
$5.49 per hamburger x 2 hamburgers=$10.98
$1.75 per soda x 4 sodas=$7
$10.98+$6.25+$12.99+$7=$37.22
$37.22 x 0.07 sales tax=approximately $2.61
$37.22 x 0.2 tip=approximately $7.44
$37.22+$2.61+$7.44=$47.27
$1.75 per soda x 4 sodas=$7
$10.98+$6.25+$12.99+$7=$37.22
$37.22 x 0.07 sales tax=approximately $2.61
$37.22 x 0.2 tip=approximately $7.44
$37.22+$2.61+$7.44=$47.27
The total amount of money paid by Bill and his friends is $47.27.
In order to determine the total cost of the lunch, the sums of the hamburgers, chicken sandwich, ribs, sodas, taxes and tips has to be determined.
The total cost of 2 hamburgers = cost of one hamburger x 2
$5.49 x 2 = $10.98
Cost of a sandwich = $6.25
Cost of ribs = $12.99
Cost of sodas = cost of one soda x 4
$1.75 x 4 = $7
The total cost of the order excluding tips and taxes = $37.22
Sales tax = percentage tax x total cost of the order excluding tips and taxes
$37.22 x 0.07 = $2.61
Amount of tips paid = 20% x total cost of the order excluding tips and taxes
0.2 x $37.22 = $7.44
Total cost of the lunch = $37.22 + $2.61 + $7.44 = $47.27
