Average cost per gallon:

(2.96 + 3.61)/2 = 3.29

Average gallons:

42.5

42.5 * 3.29 = ? average cost per month

I assume your native language is not English.

Thank you Miss sue ..

and sorry for late reply , you are right i am learning english.

so

42.5*3.29= 139.825 per month .

but i need to know the weakly cost so i divide 139.825 by 7 to get weakly price which is almost 20.

So

20 is right answer?
