In a certain year the price of gasoline rose by 20% during January, fell by 20% during February, rose by 25% in March, and fell by x% in April. The price of gasoline at the end of April was the same as it had been at the beginning of January. Find the value of x.

Respuesta :

Answer:

Fell by 25%

Step-by-step explanation:

+20% January

-20% February (20-20 is zero, so we're back to the original price we started at here)

+25% March

?? April

Currently, we are 25% more than what we had, so to get back to normal, the price needs to go down by 25 percent. This will put us back to zero. Put another way...

+20%-20%+25%-25%=0% (Original Price)
