Colin buys gas for her car at $4 a gallon. Write an equation using two variables to show the relationship between the number of gallons of gas, g, and the total amount of amount she spends, s.
The equation using two variables to show the relationship between the number of gallons of gas, g, and the total amount of amount she spends, s is:
s = 4g
Where s is the total amount of money that Colin spends and g is the number of gallons of gas purchased.
To write an equation showing the relationship between the number of gallons of gas, g, and the total amount of money spent, s, we need to consider the cost per gallon of gas and the number of gallons purchased.
Given that Colin buys gas at $4 per gallon, we can represent the cost of gallons purchased as 4g. This is calculated by multiplying the cost per gallon ($4) by the number of gallons (g).
Therefore, the equation representing the relationship between the number of gallons of gas, g, and the total amount of money spent, s, is:
s = 4g
The equation that represents the relationship between the number of gallons of gas, g, and the total amount of money spent, s, is:
s = 4g
