=======================================
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:
x= - 7 / 3
Step-by-step explanation:
1st determine the sign: -6=5x - 17 / -3
2nd move the terms: -6 = 5x + 17 / 3
3rd calculate:: -5x = 17 / 3 + 6
4th divide both sides: -5x = 35 / 3
Solution: x = - 7 / 3
