Answer:

1. august price = c + 0.25c

2. august price = 1.25c

Step-by-step explanation:

The problem statement tells us that the price of gas in August is 25% more than in July. Thus, 25% of the July price (0.25c) is added to the July price (c) to get the August price.

  c + 0.25c

The sum in the first part can be simplified by combining the coefficients of c.

  1.25c
