Answer:
regular price = $15
Step-by-step explanation:
Represent the regular price by d. Then the discount was 0.20d, and the sale price was (1 - 0.20)d, or 0.80d, which is $12.
Solving for d, we divide both sides by 0.80:
d = regular price = $15
We know the rate of the change, 3 meters per hour. And we want to know how long it will take to reach 12 meters. Say we need to reach 6 meters instead 12.
How long will that take? 2 hours! Because we divide 6 m by 3 m/h.
Now let us do the same thing will 12 meters.
12 m / 3 m/h = 4 hours
It will take 4 hours to reach the 12 meters height.
