Answer: 93
Step-by-step explanation: Since 160 cups of blend are sold , this means
A + B = 160
Since Type A is sold for 5.6 per pound , that means the total number of A sold = 5.6A
Also , Type B is sold for 4.05 per pound , the total number of B sold = 4.05B
And it was given that the total cost of blend = 751.85 , then
5.6A + 4.05B = 751.85
A + B = 160 ............................. eqn 1
5.6A + 4.05B = 751.85 ..................... eqn II
From eqn I , A = 160 - B ................ eqn III
Substitute A = 160 - B into equation II , then we have:
5.6(160 - B) + 4.05B = 751.85
Expanding , we have
896 - 5.6B + 4.05B = 751.85
896 - 1.55B = 751.85
collecting the like terms
1.55B = 896 - 751.85
1.55B = 144.15
Therefore B = 144.15/1.55
B = 93
Find the LCM between the denominators.
The LCM is 36
Divide he LCM for the denominators, then multiply the result for the numerator.
You get 25/36 and you can't simplify it
