Answer 1

One week gas was $1.25 per gallon. The next week gas was $1.50 per gallon. By 20 percentage the price increase.

Step-by-step explanation:

Here we have , One week gas was $1.25 per gallon. The next week gas was $1.50 per gallon.  We need to find that By what percentage did the price increase . Lets' calculate :

Percentage = (Next week gas - One week gas )(100)/ (One week gas)  or ,

$Percentage = \frac{((Next-week)-(One-week))(100)}{One-week}$

⇒ $Percentage = \frac{((Next-week)-(One-week))(100)}{One-week}$

⇒ $Percentage = \frac{(1.50-1.25)(100)}{1.25}$

⇒ $Percentage = \frac{(0.25)(100)}{1.25}$

⇒ $Percentage = \frac{(25)(100)}{125}$

⇒ $Percentage = \frac{(100)}{5}$

⇒ $Percentage = 20$%

Therefore, One week gas was $1.25 per gallon. The next week gas was $1.50 per gallon. By 20 percentage the price increase.
