Answer:
the cost paid by burton will be = 31.08 dollars
Step-by-step explanation:
when burton paid 36.80 for 11 and half gallons last week the cost per gallon =[tex]\frac{total cost}{total gallon}[/tex]
[tex]\frac{36.80}{11.5}[/tex]= 3.2 dollars
it is given that cost of per gallon increased by 5 percentage
5 percent of 3.2 dollar = [tex]\frac{5}{100}[/tex]×3.2 = .16 dollars
therefore the cost per gallon this week will be = 3.2 + 5 percent of 3.2 dollars
= 3.36 dollars
it is given that burton buys 9.25 gallons this week therefore his total cost will be = 9.25×cos per gallon this week
= 9.25×3.36
=31.08 dollars
