Answer:
$4.3
Explanation:
Cole bought 10 gallons of gas at the gas station with the lowest price.(the lowest price is $3.57 each gallon.) He paid with two $20 bills. Write and solve an equation to find his change.
two $20 bills = 2 * $20
= $40
Gallons of gas = 10
Lowest price of each gallon = $3.57
Cost of 10 gallons of gas = 10 * $3.57
= $35.7
Let his change = x
His change = Amount paid with - cost of gas
x = $40 - $35.7
x = $4.3
His change = $4.3
