Hello from MrBillDoesMath!
Answer:
c = d/a + b
Discussion:
I think the Question is missing a comma. Assuming you are trying to find the value "c",
a(c-b) = d => divide both side by "a"
(c-b) = d/a => add "b" to both sides
c-b + b = d/a + b => as -b + b = 0
c = d/a + b
Thank you,

You are running a fuel economy study. One of the cars you find is blue. It can travel 30 and one half miles30 1 2 miles on 1 and one fourth gallons1 1 4 gallons of gasoline. Another car is red. It can travel 25 and three fifths miles25 3 5 miles on four fifths gallon 4 5 gallon of gasoline. What is the unit rate for miles per gallon for each car? Which car could travel the greater distance on 1 gallon1 gallon of gasoline?
Blue car: 30.5 / 1.25 =24.4 miles per gallon
Red car: 25.6/0.80 =32 miles per gallon
