Aldo’s coffee shop makes a blend that is a mixture of two types of coffee. type a coffee costs 5.6 per pound. type b costs 4.05 per pound. if 160 cups of blend are sold , for a total cost of 751.85. how many pounds of type b coffee did he use ?

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

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.

answer: b)

step-by-step explanation:

its a dot plot because since the score is not high numbers.
