You work at Dave's Donut Shop. Dave has asked you to determine how much each box of a dozen donuts should cost. There are 12 don
slava [35]
A box of donuts would cost: b = 3.84 + 0.18f

First, we have to find the total cost of the donuts. 
12 x 0.32 = 3.84

Next, we need to determine the cost of the box. However, we don't know the surface area, just the cost per foot. We can multiply the number of square feet of the box by $0.18 to find the cost.

So our equation could be:  b = 3.84 + 0.18f (where f is the surface area of the box in square feet)

Find the value of x needed to make the equation true.<br> 8x – 4 = 13x + 6
Kipish [7]

Answer:

x = -2

Step-by-step explanation:

<u><em>First, you need to subtract 8x from both sides:</em></u>

8x – 4 = 13x + 6

-8x         -8x

____________

-4 = 5x + 6

<em><u>Then, subtract 6 from both sides:</u></em>

-4 = 5x + 6

-6         - 6

________

-10 = 5x

<u><em>Lastly, divide both sides by 5:</em></u>

-10 = 5x

-2 = x
