The octane rating of a gasoline is a measure of the amount of isooctane in the gas. Manufacturers recommend using 93octane gasoline on returned motors. How much 87octane gas and 95 octane gas should Yousef mix in order to make 10 gal of 93 octane gas for his returned Ford F150?

Hello again, I would like to know how to figure out how to make the equation, then solve

Hey! We have t make 93 octane and 10 gallons. so our total amount will be 0.93*10.

Moving along: total gallons will be 10. so 0.95(10x) Final equation: 0.87x + 0.95(10x) = 0.93*10

There's one more method too if this looks hard to you. Let me know if this is hard to understand.

This method looked a bit more difficult than the latter, do you have an easier method?

x + y = 10 87x + 95y = 93*10

I don't know why but my equation seems wrong... x+y=2 4x+y=5 x=y+5 4y+20+y=5 3y+20=5 3y=20+5 3y=15 3y/3=15/3 y=5 x=5+5 x=0???

How much lowfat milk(1% fat) and how much whole milk(4% fat) should be mixed to make 5 gal of reduced fat milk (2% fat)?

x + y = 5 0.01x + 0.04y = 0.02*5

Hmmm... how do you know what to put where?
 one year ago

saifoo.khanBest ResponseYou've already chosen the best response.1
It's pretty simple. For equation 1. find the total amount. it will be x+y = 5(total gallons)

SusanJaxBest ResponseYou've already chosen the best response.1
Maybe so simple that I over think and get confused! LOL
 one year ago

saifoo.khanBest ResponseYou've already chosen the best response.1
for equation 2. Now we have 3 values left. 1%, 4% and 2% We have to make 2% so: 0.01x + 0.04y = 0.02 *5 *5 because total are 5 gals.
