A recipe calls for 2.5 cups of water. What is this in mL ? ( 2 marks) Paula owns a car that has a fuel capacity of 16 US gallons. Gas costs 1.18//L . What will it cost her to fill up if the tank is already 1//4 full? ( 4 marks)

<p></p><br /><p>15. To convert from cups to milliliters, we note that 1 cup is approximately 236.6 mL. So, 2.5 cups would be equal to 2.5 * 236.6 = 591.5 mL.</p><br /><p>16. To find the cost of filling up the fuel tank, first we should know Sen Gallon is approximately 3.785 litres. Paula's car, if the tank is fully filled, holds 16 * 3.785 = 60.56 litres. But, the fuel tank is already 1/4 full, so we subtract that from the total capacity: 3/4 * 60.56 = 45.42 litres. We then multiply this by the cost of the litre, $1.18, which will give us$53.5956 (~$54).</p>
