A storekeeper wants to mix two types of flour to get 300 pounds, so he can sell it by 2.50$ per pound. If he uses flour worth $2.40 a pound with another flour worth $3.00 a pound, how many pounds of each does he use?

250 pounds cheap flour50 pounds expensive flour

Step-by-step explanation:

Let x represent the quantity of the more expensive flour. Then 300-x is the quantity of the less expensive flour. The total cost of the mix is ...

  3.00x +2.40(300-x) = 2.50(300)

  0.60x = 300(0.10) . . . . . simplify, subtract 2.40(300)

  x = 300/6 = 50 . . . . . . . . divide by 0.60. Quantity of expensive flour

  300-x = 250 . . . . quantity of cheaper flour

He should use 250 pounds of $2.40 flour, and 50 pounds of $3.00 flour.

$18.25 ($365 divided by 20)

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
