Question

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.

Answer 1

Answer: s = 4g

$4 is spent per gallon, so 4 must be multiplied with g and s does not change as it’s the amount she’s going to spend

So the answer is s = 4g

Answer 2

s = 4g ..........................................................
