Answer:
$15.21
Step-by-step explanation:
The total cost of the lunch without tax is $13. If you want to find the cost of the tip, you have to find 17% of 13. To find this you do 13×0.17 which is 2.21 dollars. Now add this to the original price of your lunch, $13, to get $15.21.
4 is 90
1 is 37
3
2 is 127
3 is 23
20ft^2
The length is currently three feet, if you add two feet to three that makes five feet. Five times four is twenty.
I hope this helps!
