we have
where
c -----> the cost in dollars
g ----> the number gallons of gas purchased
1) For g=1 gal
substitute the value of g in the equation and solve for c
The pair (1,2.95) fit the relationship
2) For g=3 gal
substitute the value of g in the equation and solve for c
The pair (3,8.85) fit the relationship
3) For g=5 gal
substitute the value of g in the equation and solve for c
The pair (5,14.75) fit the relationship
4) For c=$20.65
substitute the value of c in the equation and solve for g
The pair (7,20.65) fit the relationship
