Answer:
Time = 149.688 seconds
Step-by-step explanation:
First the conversation rate of ft to miles is
1 foot = 0.000189 mile
So 3300 feet = 3300*0.000189
= 0.6237
3300 feet = 0.6237 mile
So the roller coaster traveled 0.6237 mile.
But the speed of the roller coaster is 15 mile/hour
To calculate for time
Speed = distance/time
Time = distance/speed
Time = 0.6237/15
Time = 0.04158 hour
Converting to seconds , we multiply time by 3600
Time in seconds = 0.04158*3600
Time = 149.688 seconds

Answer:
$8,000
Step-by-step explanation:
Let minimum amount she needs to sell = x
Commission rate = 7.5%
Amount of commission = $600
7.5% of x = 600
7.5/100 * x = 600
0.075 * x = 600
0.075x = 600
x = 600/0.075
= 8,000
x = $8,000
The minimum amount she needs to sell in order to earn $600 if she earns a 7.5% commission on everything she sells is $8,000
