Acompany uses tow vans to transport workers from a free parking lot to the workplace between 7: 00 and 9: 00 a.m. one van has 6 more seats than the other. the smaller van makes two trips every morning while the larger one makes only one trip. the two vans can transport 57 people, maximum

Okay

1. take 57 - 6 = 51 
2. divide 51 by 3  = 17
3. 17+17 = 35 = how many people in the two trips that the small van made
4. 17 + 6= 23 = how many people in the one trip that the bigger van made 
5. Add 17+17+17+6= 57

Hope this helped!

Step-by-step explanation:

The gas he filled up on costed 2.63 a gallon

The gas across the street costed 2.56 per gallon

He spent 55.23 on gas, if he filled up at the station across the street he would have paid 53.76.
