A car travels $32$ miles per gallon of gasoline, and gasoline costs $\$3.60$ per gallon. To the nearest cent, what is the cost of gasoline for this car to travel $200$ kilometers? (Use $1$ mile $= 1.6$ kilometers.)

$\$14.06$

$\$22.50$

$\$36.00$

$\$11.25$

Show answer and explanation

Answer: A

First convert the distance: $200 \div 1.6 = 125$ miles. The car uses $\frac{125}{32} = 3.90625$ gallons. The cost is $3.90625 \times 3.60 \approx \$14.06$ .

Choice B treats $200$ kilometers as $200$ miles, skipping the unit conversion.
