To factor by grouping, you group up the 1st 2 terms together and the last 2 terms together and then factor those pieces.

(x^3 + x^2) + (x + 1)
x^2(x + 1) + 1(x +1) - now factor out the (x + 1)
(x + 1)(x^2 + 1) - final answer

Hunter needs 10 oz of a snack mix, seeds cost $1.50 per ounce and fruit costs $2.50 per ounce. The 10 oz snack mix costs $2.20 p
vichka [17]

Answer:

the hunter should purchase three ounces of seeds and 7 ounces of dried fruit to satisfy the situation

Step-by-step explanation:

Let us assume the amount of seeds be x

And, the amount of dried fruit be y

Now the first equation would be

x + y = 10

y = 10 - x

And, the second one would be

1.50x + 2.50y = 2.20(10)

1.50x + 2.50y = 22

We can put the y value in second equation

1.50x + 2.50(10 - x) = 22

1.50x + 25 - 2.50x = 22

-x = 22 - 25

-x = -3

x = 3

and, y = 10 - 3

= 7

Hence, the hunter should purchase three ounces of seeds and 7 ounces of dried fruit to satisfy the situation
