<span>So, what you need to take into consideration here is the order of operations. First, you have to multiply 3 by 6 and then do the rest of the question in the order it is written. So, here is how to calculate this: 3 - 3x6 +2 = 3 - 18 + 2 = -15 + 2 = -13. The correct answer is -13.Hope this helps. Let me know if you need additional help!</span><span />

A grocery store offers a cheese sampler that includes a pepper cheddar cheese that costs $15 per kilogram and Pennsylvania Jack

lawyer [7]

Answer: The quantity of pepper cheddar cheese required = 2.5 kilograms

The quantity of Pennsylvania Jack required = 4.5 kilograms

Step-by-step explanation:

Let x = Quantity of pepper cheddar cheese

y= Quantity of Pennsylvania Jack

As per given , we have the following system of equations:

$x+y=7----------(1)\\\\ 15x+8y= 7\times10.50\\\\ 15x+8y=73.5------------(2)$

Multiply 8 to equation(1) , we get

$8x+8y=56---------(3)$

Eliminate (3) from (2) , we get

$7x=17.5\\\\ x=\dfrac{17.5}{7}=2.5$

Put value of x in (1) , we get

$2.5+y=7\\\\ y=7-2.5=4.5$

Hence, the quantity of pepper cheddar cheese required = 2.5 kilograms

The quantity of Pennsylvania Jack required = 4.5 kilograms

Okay sub equation 2 into equation 1:

x + 3x = 8
4x = 8
x = 2

then 2 + y = 8, therefore y = 6
So the answer is B
