Step-by-step explanation:

Given:

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.

Question:

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 =

Similarly,

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.

step-by-step explanation:

well if you round, things become much more simple. round 5.95 to 6, 4.25 to 4, and 1.05 to 1. now, add 6+4+1 and that would equal 11. so the items together would equal to about $11.
