The total cost of gasoline varies directly with the number of gallons purchased. Gas costs $1.89 per gallon. Write a direct variation to model the total cost for g gallons of gas. (1 point) g = 1.89g; c = g + 1.89; c = 1.89g; c = g/1.89

Answer 1

To model the total cost \( c \) for \( g \) gallons of gas, where the cost per gallon is $1.89, the correct equation for direct variation is:

\[ c = 1.89g \]

So the answer is: c = 1.89g.
