If the mixture is P% gasoline, prices at $1.60 per gallon, and (100-P)% alcohol,
priced at $1.00 per gallon, write a formula for the price of a gallon of gasahol.
:
p = per cent gasoline
:
f(p) = price of a gallon of gasahol.
:
f(p) =
+
; is the gasahol formula
:
:
We can test our formula using 50% gasoline, it should be $1.30
:
f(50) =
+
f(50) =
+
f(50) = .80 + .50
f(50) = $1.30
