Premium gasoline costs $4.33 per gallon. Noni’s car holds 11.6 gallons of gas. What is the estimated cost of filling the tank of Noni’s car?

Multiply the price per gallon by the tank’s capacity: $4.33 × 11.6 ≈ $50. To estimate, round $4.33 to $4 and 11.6 to 12, giving $4 × 12 = $48. So the estimated cost is $48, choice B.
