Answer:
90 pounds, 210 pounds
Step-by-step explanation:
<u>Given</u>:
A storekeeper wants to mix two types of flour to get 300 pounds, so he can sell it by 2.50$ per pound.
He uses flour worth $2.40 a pound with another flour worth $3.00 a pound.
<u>Question</u>:
How many pounds of each does he use?
Solution:
Let pounds of one type of flour mixed =
Then pounds of another type of flour mixed =
Cost of 1 pound of one type of flour = $2.40
Cost of pounds of one type of flour =
<u>Similarly</u>,
Cost of 1 pound of another type of flour = $3
Cost of pounds of another type of flour =
Cost of mixed flour per pound = $2.5
Total cost of mixed flour per pound = $2.5 300 = $750
Cost of pounds of one type + Cost of
pounds of another type = $750
Pounds of one type of flour mixed = = 90 pounds
Pounds of another type of flour mixed = = 300 - 90 = 210 pounds
Thus, 90 pounds of one and 210 pound of another type of flour mixed.
