=======================================
Explanation:
Jump to the last part of the question where it asks "how many pounds of type A coffee were used?". Since this is the goal we want to reach, let's make x the amount of type A used (in pounds).
This means that 3*x pounds of coffee were used for type B, since 3 times as much type B was used as type A. Example: if you use 2 pounds of type A, then you'll have 6 pounds of type B.
Type A costs 4.45 dollars per pound. If you use up x pounds of it then it costs a total of 4.45*x dollars. Type B costs 5.80 dollars per pound and if you use 3*x pounds, then it costs you 5.80*3x = 17.40x dollars. The total cost of both types is going to be 4.45x+17.40x = 21.85x dollars.
Set this equal to 568.10 and divide both sides by 21.85 to isolate x
21.85x = 568.10
21.85x/21.85 = 568.10/21.85
x = 26
We used 26 pounds of type A coffee

Answer:
Amount of hay in first barn = 90 tons
Amount of hay in second barn song = 30 tons
Step-by-step explanation:
Let the amount of hay in second barn be x, then hay in first barn will be 3x.
20 tons of hay was removed from first barn and ws added to second barn.
Now, the amount of hay in first barn = 3x -20
Amount of hay in second barn = x+20
The equation now formed is:
x+20 = (3x-20)
7x+14 = 15x -100
-8x = -240
8x = 240
x = 30
3x = 90
Amount of hay in first barn = 90 tons
Amount of hay in second barn song = 30 tons
Is there any options to choose from
