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?
