Question

1. The equation c = 2.95g shows how much it costs to buy gas at a gas station on a

Answer 1

Answer:

see the procedure

Step-by-step explanation:

we have

$c=2.95g$

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

$c=2.95(1)$

$c=\ 2.95$

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

$c=2.95(3)$

$c=\ 8.85$

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

$c=2.95(5)$

$c=\ 14.75$

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

$20.65=2.95g$

$g=20.65/2.95$

$g=7\ gal$

The pair (7,20.65) fit the relationship
