Answer:

A)Equation that represents the situation :  7x+2x=4500

B)Regular gas sold = 7x = 7(500)=3500

Premium gas sold = 2x =2(500)=1000

Step-by-step explanation:

We are given that The ratio of gallons of regular gas sold to gallons of premium gas sold is 7:2.

Let the ratio be x

Regular gas sold = 7x

Premium gas sold = 2x

We are also given that A gas station sells a total of 4500 gallons of regular and premium gas in one day.

So, 7x+2x=4500

9x=4500

x=500

A)Equation that represents the situation :  7x+2x=4500

B)Regular gas sold = 7x = 7(500)=3500

Premium gas sold = 2x =2(500)=1000
