1. The equation c = 2.95g shows how much it costs to buy gas at a gas station on a
certain day. In the equation, c represents the cost in dollars, and g represents how
many gallons of gas were purchased.
a. Write down at least four (gallons of gas, cost) pairs that fit this relationship.

Answer:

see the procedure

Step-by-step explanation:

we have

[tex]c=2.95g[/tex]

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

[tex]c=2.95(1)[/tex]

[tex]c=\$2.95[/tex]

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

[tex]c=2.95(3)[/tex]

[tex]c=\$8.85[/tex]

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

[tex]c=2.95(5)[/tex]

[tex]c=\$14.75[/tex]

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

[tex]20.65=2.95g[/tex]

[tex]g=20.65/2.95[/tex]

[tex]g=7\ gal[/tex]

The pair (7,20.65) fit the relationship
