Question

Please help, a and b

Answer 1

A. Alexander, 1.2

B. 39 pounds

Explanation:

You want to find the price per liter. For Lois, you want to divide 17.4 by 12 to get the unit price which will be 1.45. So Lois cost 1.45 per liter.

You also want to find the unit price for Alexander. You want to divide 22.8 by 19 to get the price per unit which is 1.2.

1.2 is less than 1.45 so Alexander is better in value.

Now for Part b, you want to multiply 1.2 by 30 because it is the cheaper station and you will get 39. So it will cost 39 for 30 liters of patrol.

Hope this helps!
