Answer:
Step-by-step explanation:
From the question, we are informed that the price of a gallon of gas in one month was $2.60 and that the following month, the price was $2.99.
Change in price = New price - Old price
= $2.99 - $2.60
= $0.39
Percentage increase= Change in price/Old price × 100
= 0.39/2.60 × 100
= 0.15 × 100
= 15%
The percent increase in the price of one gallon of gas is 15%.
