Answer:
Amount of Type B coffee used = 99 pounds
Step-by-step explanation:
Let the amount of type A taken be x pounds and type B taken be y pounds.
But we know that the total amount of coffee used = 177 pounds.
Type A coffee costs $5.70 per pound and type B coffee costs $4.10 per pound.
The total cost for the blend = $850.50.
We have to find the pounds of type B coffee used.
Equating the total costs,
5.70x + 4.10y = 850.50
x + y = 177
Substitute x = 177 - y in the first equation.
5.70 + 4.10y = 850.50
158.40 = 1.60 y
y = = 99
Amount of Type B coffee used = 99 pounds
