Answer:
see the procedure
Step-by-step explanation:
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

Answer:
Greg's savings: 19 x 1

57 / 3 = 19
19 is prime, so Greg's savings has to be 19 x 1.
for the implicit integration I got:

the vertical tangent would at points at which y' goes to infinity.
that happen when the right-hand side has singularities, that is, the denominator is 0:

so the two points y above have a vertical tangent.
