Well, we need to divide $36.25 by 12.5. This will give us the per gallon price. So 36.25/12.5=2.90. So regular gasoline is $2.90 a gallon So, now we know this, if we add 14¢ to 2.90, we get $3.04. Now, we multiply 3.04 by 12.5=38. So, 12 and a half gallons of premium gas costs $38
multiply 12,000 ans 6.9 as a decimal so it would be 12,000*0.69 then you multiply your answer 8280 with the time which is 5 and you get your answer i think not sure
