Question

if you drive 115 km per day, how much money would you spend on gas in one week if gas costs 1.10 euros per liter and your car's gas mileage is 41.0 mi/gal ? Assume that 1euro=1.26dollars .

Answer 1

Answer:

$63.98

Explanations:

Accordint to the question, if you drive 115 km per day, the distance covered in a week will be expressed as;

$\begin{gathered} distance\text{ }in\text{ }a\text{ }week=7\times115 \\ distance\text{ }in\text{ }a\text{ }week=805km \end{gathered}$

Convert kilometers to miles

Convert 805km to miles

805km = 500.204miles

Convert miles to gallons

Since 41.0miles = 1 gallon

500.204miles = 12.195gallons

This shows that the total gallons used in a week is 12.195gallons

Convert gallons to litres

1 gallon = 3.78541litres

12.195gallons = 46.163 litres

If the gas costs 1.10 euros per liter, the cost of 46.163 litres will be 50.78 euros (1.10* 46.163)

Assuming that 1euro = 1.26dollars, the amount of money spent on gas for a week in dollars will be (1.26 * 50.78) which is $63.98

500.204miles =
