There are 45 pounds and 30 pounds of each type respectively.

Step-by-step explanation:

Since we have given that

Cost of first type = $2 per pound

Cost of second type = $7 per pound

Cost of mixture = $4 per pound

So, we need to find the quantity of each type to make 75 pounds of a blend.

We will use "Mixture and Allegations":

First type Second type

2 7

4

---------------------------------------------------

7 - 4 : 4 - 2

3 : 2

So, Quantity of first type would be

$\dfrac{3}{5}\times 75=3\times 15=45\ pounds$

Quantity of second type would be

$\dfrac{2}{5}\times 75=2\times 15=30\ pounds$

Hence, there are 45 pounds and 30 pounds of each type respectively.
