How many quarts of peanut oil worth 19 cents per quart must be mixed with 100 quarts worth 25 cents per quart to produce a mixture worth 24 cents per quart?

20 quarts of peanut oil worth 19 cents per quart must be mixed.

Explanation

Lets assume, x quarts of peanut oil worth 19 cents per quart must be mixed.

Now we are mixing 100 quarts of another peanut oil worth 25 cents per quart with that x quarts. So, the total amount of the mixture quarts, which will worth 24 cents per quart.

Total price of x quarts oil cents

Total price of 100 quarts oil cents

and total price of the mixture cents

So the equation will be :

answer:      

step-by-step explanation:

connie < felicia < stew

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4
