Answer:
This is a good tip and $18 is 18% of what the meal cost.
Step-by-step explanation:
On average the proper tip is 15% of the cost of your meal cost. In this case you have paid 18% of your meal cost.
1584 yards cubed.
Convert all the measurements to inches.
9*12=108
11*12=132
Multiply 108 and 132 to get the area.
108*132=14256
Multiply 14256 by 4 to get the volume.
14256*4=57024
Divide by 36, because there are 36 inches in a yard.
57024/36= 1584 Yards Cubed
