Question
1.
The total cost of gasoline varies directly with the number of gallons purchased. Gas costs $1.77 per gallon. Write a direct variation to model the total cost c for g gallons of gas.
g = 1.77c
c = 1.77g
c = g + 1.77

To model the total cost \( c \) for \( g \) gallons of gas that costs $1.77 per gallon, we can write the equation using direct variation.
The correct equation is:
\[ c = 1.77g \]
This means that the total cost \( c \) is directly proportional to the number of gallons \( g \) purchased, with $1.77 as the constant of variation (the cost per gallon).
The correct equation is:
\[ c = 1.77g \]
This means that the total cost \( c \) is directly proportional to the number of gallons \( g \) purchased, with $1.77 as the constant of variation (the cost per gallon).
