Answer:
The height h it will travel in t minutes
Height h = 6 + 20(t)
Oh=20t + 6
Step-by-step explanation:
A hot air balloon starts at a height of 6 feet above the ground and then rises at a rate of 20 feet each minute.
Initial height h0 = 6 feet
Then it travel 29 feet each minute
Rate = 20 feet/ minute
The height h it will travel in t minutes
Height h = 6 + 20(t)
the answer would be 240 because wind speed is close to its median
15% = 0.15
multiply the bill ( 42.00) by 0.15 for the amount of tip
42.00 * 0.15 = 6.30
the tip = $6.30
