First, we divide the amount of tip which is $16 by the amount that is used to pay the food bill which is $80. Then, multiply the quotient by 100%. Mathematically,
($16 / $80) x 100% = 20%
Thus, you left 20% of the food bill for the tip.

PLEASE let me know if this is correct.
Answer:
first you have to figure out what is y.
Step-by-step explanation:
Then you would have to subtract and add.
The actual speed of the plane with the wind:
v² = ( 150 + 50 · cos 45°)² + ( 50 · sin 45°)²
v² = ( 150 + 35.355 )² + 35.355²
v² = 34,356.467 + 1,249.976
v = √35,606.452
v = 188.7 mph
