fuel cost involved in idling your car for 5 minutes per day when the cost of gasoline is $3.75 using formula c=19a-4 where c is the cost and a is the size of the engine in liters. Determine the size of the engine in your car and find the cost of idling your car for 5 minutes a day. cost of gasoline is $3.75 and engine size is 4.0 liters
I think I figured it out. Please let if I figured it out right or not please someone.
if a=4, then c=19(4)-4
c=19(4)-4
c=19*4=76
76-4=72
c=72
Did I do this problem right?????????????

This is a very poorly worded question. !!
fuel cost involved in idling your car for 5 minutes per day when the cost of gasoline is $3.75(per gallon) using formula c=19a-4 where c is the cost (I will assume this is in cents) and a is the size of the engine in liters. Determine the size of the engine in your car and find the cost of idling your car for 5 minutes a day. cost of gasoline is $3.75(per gallon) and engine size is 4.0 liters
C = 19a - 4
C is total cost - not the cost of per gallon
a=4
C=19*4 - 4
C = 76 -4
C = 72 cents
so yes guest - you interpreted the question the same as I did but really the question did not make sense. :)
