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?

Answer 1

I'm sorry, but I misread your question.

Divide 139.825 by 4 to find the weekly cost = $34.96 per week

Answer 2

Thank you so much .

Answer 3

You're welcome.
