If you have a part and a whole you can subtract the part from the whole to find the other part.
I'm not sure about it, but that's my best guess ;3
Good luck!

how many pounds of candy worth $12 per pound should be mixed with candy costing $19 per pound to produce a 70 pound mixture that

sweet-ann [11.9K]

Answer:

40 pounds

Step-by-step explanation:

Given: Cost of a candy $(c_1)$ = $\$ 12$ per pound

Cost of candy $(c_2) = \$ 19\ per\ pound$

Total amount of mixture of be produced = $70\ pound$

Selling price of mixture = $\$ 15 \ per\ pound$

Let´s x be the amount of $c_1$ to be mixed in the mixture.

∴ Cost of $c_1$ in the mixture = 12x

Next, Cost of $c_2$ in the mixture = $(70 - x)\times 19$

And we know the cost of final mixture = $70 \times 15 = 1050$

Now, putting all the value in the equation

⇒ $12x + 19 \times (70 - x) = 1050$

⇒ $1330 - 7x = 1050$

⇒ $-7x = -280$

∴ $x = 40\ pound$

∴ 40 pounds of candy worth $12 per pound to be mixed in the mixture.

What is the x And y intercept of (10,0) and (0,-10)

Radda [10]

The y-intercept is found by letting x = 0 and finding / calculating y. That would be (0, -10).

The x-int. is found by letting y = 0 and finding x. That would be (10,0).
