Manufacturers recommend using 93-octane gasoline on returned motors. How much 87-octane gas and 95-octane gas should Yousef mix in order to make 10 gallons of octane for his returned F-150?
------------------------------
Equation:
iso + iso = iso
0.87x + 0.95(10-x) = 0.93*10
---------------------------------
Multiply thru by 100 to get:
87x + 95*10 - 95x = 93*10
----
-8x = -2*10
x = 2.5 gallons (amt. of 87-octane needed)
---
10-x = 7.5 gallons (amt. of 95-octane needed)
----------
